Background and Objectives: Hysterectomy is one of the most frequently performed gynecological surgical procedures worldwide. It is well established that the laparoscopic approach offers better outcomes for patients compared to abdominal hysterectomy. However, the technique for vaginal cuff closure during laparoscopic hysterectomy (TLH) remains insufficiently standardized in the international literature. Based on our results, we aim to demonstrate that closure of the vaginal cuff using a figure-of-eight suture is a sufficient, reproducible, time-efficient and safe method during total laparoscopic hysterectomy. Materials and Methods: Our retrospective observational study analyzed 173 patients who underwent a TLH from January 2016 to December 2021 at the University of Debrecen, Department of Obstetrics and Gynecology. Standardized surgical steps were applied in all cases (ligation of the uterine arteries at their origin, fenestration of the broad ligament above the ureter), and the vaginal cuff was closed laparoscopically with an absorbable suture, incorporating vesicovaginal fascia, vaginal mucosa and uterosacral ligaments. Patient demographics, operative data, and perioperative outcomes were extracted and analyzed. Results: TLH was successfully performed in 173 cases, and no conversion to open surgery was necessary. The mean age of the patients was 51.4 (23–86) years, the median body mass index (BMI) was 26.9 (16.9–45) kg/m², and the operative time was 92 (35–240) minutes. The mean uterine weight was 151 (16–440) g. The mean hemoglobin drop was 15.8 (0–44) g/L after the surgery. Regarding complications, ureteral injuries occurred in two cases (1.2%). One patient (0.6%) required relaparotomy due to rectosigmoid perforation. Postoperative complications included vaginal cuff dehiscence in two cases (1.2%), with one patient (0.6%) requiring resuturing, fever in six cases (3.5%), vaginal discharge in four cases (2.3%), and vaginal bleeding in one case (0.6%). Pulmonary embolism occurred in one patient (0.6%). Three patients (1.7%) required blood transfusion based on postoperative blood counts. Conclusions: Our results demonstrate an acceptable operative time and a low rate of postoperative complications, suggesting that closing of the vaginal cuff with a figure-of-eight suture is a sufficient and safe technique. This method can be reliably reproduced and incorporated into the standardized steps of total laparoscopic hysterectomy. Full article

Background and Clinical Significance: Metallic stents represent a breakthrough in the treatment of ureteric obstruction, improving patient quality of life. Despite their advantages, management of encrustation remains a difficult complication to address. This case series highlights the rare occurrence of permanent ureteral Wallstents remaining indwelling for over 20 years. It emphasizes that the function of these older devices can be successfully preserved using minimally invasive techniques. Case Presentation: This case series details three patients, two males, aged 75 and 69 years, diagnosed with colon cancer, and one female, aged 67 years, with cervical cancer, who presented with obstructive uropathy due to extrinsic malignant compression. As a therapeutic strategy, permanent ureteral Wallstents were placed in all three patients. Over time, the stents developed significant encrustation, leading to secondary obstruction. Clinical manifestations of this complication varied, ranging from asymptomatic hydronephrosis to acute symptomatic uropathy characterized by fever and localized pain. All cases were treated endoscopically with Ho:YAG laser lithotripsy, and urine flow was successfully restored. During the follow-up period, one patient experienced two recurrences that were managed with the same technique, another remained completely symptom-free, and the third was lost to long-term follow-up. Remarkably, the stents have remained functional for over 20 years post-implantation. Conclusions: This is a rare report documenting permanent ureteral Wallstents with such prolonged indwelling time. Furthermore, our findings suggest that through minimally invasive techniques, the function of these devices can be successfully preserved. Full article

Objective: The aim of this study was to evaluate the safety and efficacy of robot-assisted laparoscopic ureteroureterostomy (RALUU) and laparoscopic ureteroureterostomy (LUU) for duplicated kidney malformations in infants. Methods: This retrospective comparative cohort included infants with duplicated kidney malformations who underwent RALUU or LUU between May 2021 and April 2025. Perioperative variables assessed included operative duration, blood loss, oral feeding time, FLACC pain score, hospital stay, and complications. Follow-up outcomes included changes in anteroposterior pelvic diameter (APD), ureteral diameter (UD), and renal function (RF) of the affected upper moiety, assessed using renal ultrasonography and radionuclide imaging, with preoperative measurements serving as the baseline reference. The minimum follow-up duration was 12 months. Surgical success was determined based on fulfillment of all three criteria: resolution or alleviation of clinical symptoms, a reduction in APD and UD, and preserved or improved upper-moiety renal function compared with baseline. Results: The final cohort consisted of 52 infants (RALUU, n = 28; LUU, n = 24). Demographic and clinical profiles were comparable between groups. RALUU was associated with a shorter operative duration than LUU (139.6 ± 16.6 vs. 151.8 ± 21.6 min, p = 0.029). Estimated blood loss, time to oral feeding, FLACC pain score, and hospital stay were comparable. Postoperative complications were observed in 2 RALUU patients and 3 LUU patients. One patient in the LUU group developed urine leakage, which was managed conservatively. Postoperative urinary tract infection occurred in 2 patients in each group. No patient required secondary surgery. At a mean follow-up of 26.8 ± 10.4 and 28.1 ± 11.7 months in the RALUU and LUU groups, both groups showed significant reductions in APD and UD, with preserved RF and a modest postoperative increase. Conclusions: Both RALUU and LUU were safe and effective for duplicated kidney malformations in infants. RALUU was associated with a shorter operative time, while postoperative recovery, complication rates, and follow-up outcomes were comparable. Full article

Background and Clinical Significance: Spontaneous renal forniceal rupture is an uncommon complication of obstructive uropathy and is classically associated with ureteric calculi rather than distal urinary retention. Bilateral retention-related rupture appears to be exceptionally rare and may be diagnostically challenging when renal function begins to improve after bladder decompression; Case Presentation: An 82-year-old man with a history of prostate cancer treated five years earlier with external beam radiotherapy and androgen deprivation therapy presented with acute abdominal pain radiating to both flanks and inability to void. Bedside ultrasonography showed urinary retention and bilateral hydronephrosis, and a 16-Fr Foley catheter drained 900 mL of urine. Admission evaluation showed severe acute kidney injury, microscopic hematuria, minimal leukocyturia, and elevated inflammatory markers. Post-obstructive diuresis developed after bladder decompression. CT urography with excretory-phase imaging on hospital day 3 demonstrated severe bilateral hydroureteronephrosis with bilateral renal forniceal rupture and associated urinomas, including a larger left-sided collection extending toward the psoas compartment. Bilateral percutaneous nephrostomies were placed on hospital day 4 for upper-tract diversion. Immediate nephrostography showed no active contrast extravasation. At one-month follow-up, combined CT and nephrostographic assessment confirmed complete resolution of the bilateral urinomas without persistent leak, and the nephrostomy tubes were removed; Conclusions: This case suggests that urinary retention in an older man with prior prostate radiotherapy may reflect radiation-associated outlet pathology and/or impaired detrusor function rather than simple prostate enlargement. Delayed-phase CT urography was essential for diagnosis, and active bilateral diversion was justified by bilateral rupture, acute kidney injury, and the extent of urinary extravasation. The report expands the limited PubMed-indexed literature on retention-related upper urinary tract rupture and supports cautious follow-up aimed at defining the underlying mechanism of retention.

Hydronephrosis caused by malignant ureteral obstruction or radiotherapy-induced ureteral stenosis is a frequent complication in patients with cervical cancer. Effective management requires continuous urinary drainage, which can be achieved either internally through ureteral stent placement or externally via percutaneous nephrostomy. Among available devices, the Allium^TM fully covered nitinol mesh ureteral stent is designed to treat ureteral or urethral strictures while allowing safe and easy removal. However, serious complications have been reported, including uretero-enteric, uretero-arterial, and uretero-vaginal fistulas, pseudoaneurysm, ureteral perforation and sepsis. We report the case of a 44-year-old woman diagnosed in 2020 with stage IIIC1 cervical cancer (FIGO classification) who underwent surgery followed by adjuvant radiotherapy. In 2021, a right metallic ureteral stent was placed to treat ureteral obstruction. Two years later, she presented with right lumbar pain, and abdominal ultrasonography revealed grade III right hydronephrosis. CT scan demonstrated migration of the metallic ureteral stent into the rectal wall. Endoscopic extraction of the migrated stent was successfully performed via colonoscopy. Retrograde pyelography and CT imaging confirmed the presence of a recto-ureteral fistula. A 6 Ch/26 cm double-J ureteral stent was subsequently placed with good positioning and drainage. At the six-month follow-up, replacement of the double-J stent was performed. Imaging studies showed only minor residual hydronephrosis. Although metallic ureteral stents are effective for managing malignant ureteral obstruction, particularly in complex oncologic cases, they are not free of severe complications. The risk appears increased in patients who have undergone radiotherapy, emphasizing the need for careful monitoring and long term follow-up. Full article

Background/Objectives: Midurethral sling (MUS) surgery is a standard treatment for stress urinary incontinence in women. Obturator-route MUS procedures reduce retropubic morbidity, but rare concealed hemorrhagic complications can be severe and rapidly progressive. This report describes a complex case of life-threatening hemorrhage, upper urinary tract extravasation, and delayed infection involving a persistent pelvic collection after obturator-route MUS. Methods: We reviewed the clinical course, imaging findings, interventions, and follow-up of a 77-year-old woman who developed severe complications after outpatient obturator-route MUS. A descriptive narrative summary of published hemorrhagic complications after TOT or TVT-O procedures was also performed. Result: On postoperative day 1, the patient presented with left lower abdominal pain, dizziness, vomiting, tachycardia, and severe anemia. Contrast-enhanced computed tomography showed active bleeding from the left obturator artery, an 11.5 cm pelvic hematoma with bladder displacement, and upper urinary tract contrast extravasation at the left renal pelvis and ureteropelvic junction. Emergency transcatheter arterial embolization and left percutaneous nephrostomy were performed, followed by delayed antegrade double-J ureteral stenting. Four months later, she developed E. coli urosepsis with a persistent 7.9 cm paravesical collection. Persistent symptoms despite initial antibiotic therapy required broad-spectrum antibiotics and percutaneous catheter drainage. The drainage fluid was serous, and S. hominis isolated from the drainage culture was interpreted as a contaminant; therefore, the collection was managed as a clinically suspected infection involving a persistent pelvic collection rather than as a microbiologically confirmed infected hematoma. Conclusions: After obturator-route MUS, severe abdominal or pelvic pain, dizziness, tachycardia, hypotension, or abrupt hemoglobin decline should prompt contrast-enhanced CT to evaluate for concealed pelvic arterial bleeding and associated urinary tract extravasation. Early multidisciplinary coordination and follow-up of persistent pelvic collections may be important in complex cases. Full article

Schistosomiasis (bilharzia) is a parasitic infection caused by trematodes of the Schistosoma genus and remains a significant health burden in endemic regions. Granulomatous host responses to deposited Schistosoma eggs in small veins and tissues result in progressive changes and characteristic imaging findings. This diagnostic radiological review synthesizes the published literature and highlights key and robust imaging findings that facilitate the diagnosis of Schistosoma mansoni and Schistosoma haematobium, with emphasis on modality-specific patterns and disease staging. Schistosoma mansoni primarily affects the liver, causing periportal fibrosis visible as “pipe-stem” echogenic thickening upon ultrasonography, which may progress to portal hypertension and chronic liver disease. Liver cirrhosis is the end-stage disease manifested as an irregular liver contour with surface nodularity and lobar redistribution as right lobe atrophy with left and/or caudate lobe hypertrophy. Schistosoma haematobium predominantly affects the genitourinary system, causing urinary bladder wall thickening and calcification. Early disease, within three months of infection, may present with fine calcification, firstly in the bladder base and then extending to the whole bladder and even to the ureters. Calcification appears as a line or two parallel lines on radiography and as a circle in axial computed tomography (CT) images, which is pathognomonic for early-stage Schistosomiasis. In contrast studies, including conventional urography and CT urography, Schistosoma eggs appear as bubble-like filling defects in the ureter, kidney, and bladder, manifested as ureteritis, pyelitis, and cystitis cystica. Late stages appear as coarse calcification, fibrosis, strictures, and reduced bladder capacity and are associated with an increased risk of bladder squamous cell carcinoma. Moreover, Schistosomiasis calcification can present in genital organs, especially in the seminal vesicles; in the prostate in males; and in the vulva, cervix, and perineum in females. Ultimately, Schistosoma mansoni and haematobium eggs can reach the spinal cord, leading to acute myelopathy with paraparesis, urinary retention, or paraplegia. Recognition of characteristic imaging patterns of Schistosomiasis is essential for early diagnosis, accurate staging, and prevention of long-term complications. Full article

Background/Objectives: Acute kidney injury (AKI) is a clinically important complication among hospitalized urology patients. However, data from general urology inpatient populations remain limited. We aimed to assess AKI frequency in a monitored urology inpatient cohort, identify associated predictors, and develop an exploratory admission-based risk stratification model. Methods: We conducted a retrospective observational cohort study of adults admitted to a tertiary urology ward between June 2023 and May 2024 who had at least two serum creatinine measurements during hospitalization. AKI was defined according to Kidney Disease: Improving Global Outcomes (KDIGO) serum creatinine criteria. Demographic, clinical, laboratory, and procedural data were analyzed. Multivariable logistic regression identified factors associated with AKI and was used to construct a reduced exploratory admission-based risk model. Results: Among 196 monitored patients, 67 (34.2%) developed AKI during hospitalization, and 82.1% had KDIGO Stage 1 AKI. Higher admission serum creatinine, hypertension, nephrolithiasis, and ureteral interventions were independently associated with AKI. AKI was also associated with longer hospitalization (6.4 ± 4.2 vs. 5.1 ± 3.2 days, p = 0.044). The reduced exploratory model identified low-, intermediate-, and high-risk groups with progressively increasing AKI incidence (7.7%, 32.3%, and 76%, respectively; AUC = 0.76). Conclusions: In this monitored cohort, AKI was frequent and associated with admission characteristics and prolonged hospitalization. These findings support targeted renal monitoring in higher-risk patients. The admission-based risk model is exploratory and requires validation in prospective multicenter cohorts before clinical implementation. Full article

Background/Objectives: Phillygenin (PHI), a natural lignan derived from Forsythia suspensa, has garnered attention for its potential to alleviate chronic diseases, including chronic colitis, pulmonary fibrosis, and diabetes. Chronic kidney disease (CKD) poses a global health challenge, characterized by high morbidity and mortality rates and associated with a spectrum of secondary complications. In this study, we aim to investigate the therapeutic effectiveness of PHI on CKD and also identify molecular signals by using a unilateral ureteral obstruction (UUO) mouse model and in vitro experiments. Methods: C57BL/6 mice were administered PHI at 50 mg/kg/day to assess its therapeutic effectiveness. In vitro, lipopolysaccharide (LPS) and adenosine triphosphate (ATP) were used to induce pyroptosis, also known as pyroptosis, in renal proximal tubular cells (NRK52E). Results: After PHI treatment for 14 consecutive days, the collagen deposition and extracellular matrix (ECM) accumulation, the expression of oxidative stress response proteins (catalase, superoxide dismutase 2, NADPH oxidase 4, and thioredoxin reductase 1), pro-inflammatory markers (TNF-α and Cyclooxygenase-2(COX-2), and infiltration of neutrophils and macrophages were significantly ameliorated in the UUO mice. Interestingly, the pyroptosis-related proteins (NLRP3/Caspase-1/GSDMD/IL-1β) and cell apoptotic death were also conspicuously relieved after treatment with PHI. Furthermore, PHI administration significantly attenuated the ATP/LPS-induced NF-κB/NLRP3/Caspase-1/GSDMD pyroptosis signal pathway in NRK52E cells. Conclusions: These results demonstrate, for the first time, that PHI treatment ameliorates inflammation and the related pyroptosis via inhibitory regulation of the NF-κB/NLRP3/Caspase-1/GSDMD axis, leading to attenuated renal fibrosis and progressive CKD in UUO mice and in vitro. Our findings suggest that PHI could be a nutraceutical candidate for attenuating CKD progression. Full article

Background/Objectives: Ureteral complications following oblique lumbar interbody fusion (OLIF) are uncommon and are typically attributed to direct mechanical injury. Functional ureteral obstruction without overt ureteral damage remains poorly characterized. We report two cases that provide clinical and intraoperative evidence of a previously underrecognized mechanism of ureteral obstruction associated with anterior cage positioning during OLIF. Case Presentation: Among 180 OLIF procedures performed by a single surgeon, two cases (1.1%) of postoperative or intraoperative ureteral compromise without direct structural injury were identified. In the first case, postoperative imaging revealed hydronephrosis and focal angulation of the left proximal ureter at the level of the interbody cage, without contrast extravasation. The obstruction was managed with double-J ureteral stenting, and serial renal function monitoring confirmed preserved renal function throughout the clinical course. In the second case, retroperitoneal tissue including the ureter was directly observed intraoperatively to be interposed between the anterior longitudinal ligament and the interbody cage during anterior cage placement. Release of the interposed tissue resulted in immediate ureteral decompression without structural damage. Correlation of the postoperative findings in the first case with the intraoperative observations of the second case supports a unified mechanistic explanation: anterior cage advancement may draw retroperitoneal tissue into the cage–anterior longitudinal ligament interface, subjecting the ureter to focal compression or angulation. Conclusions: Functional ureteral obstruction during OLIF may occur secondary to retroperitoneal tissue interposition rather than direct ureteral trauma. Awareness of this mechanism and meticulous protection of the anterior retroperitoneal layer during cage advancement may help prevent avoidable ureteral complications. Full article

Background/Objectives: Ureteric stents are commonly used in the management of urolithiasis but are associated with significant morbidity, leading to unplanned emergency department presentations and increased healthcare utilisation. This study aimed to evaluate whether reducing ureteric stent dwell time from three months to one month was associated with reduced stent-related emergency presentations. Secondary objectives were to assess post-ureteroscopy infective complications and identify predictors of emergency attendance. Methods: A retrospective cohort study was conducted across Western Sydney Local Health District, comparing patients undergoing ureteric stenting prior to ureteroscopy before (n = 189) and after (n = 244) an institutional policy change reducing time to definitive surgery from three months to one month. Patients aged ≥16 years with urolithiasis were included. Results: Following the policy change, mean waiting time for ureteroscopy decreased from 97.3 to 40.6 days. The proportion of patients presenting to the emergency department (ED) for stent-related symptoms decreased from 31.7% to 16.4% (p < 0.001), and mean presentations per patient declined from 0.60 to 0.21 (p < 0.001). Stent irritation accounted for most presentations. Using multivariable analysis, age < 50 years, immunosuppression, and positive pre-operative urine cultures were independently associated with ED attendance. Post-ureteroscopy infective complications were lower in the shortened dwell-time cohort (2.0% vs. 4.2%) but did not reach statistical significance (p = 0.26). Conclusions: Reducing routine ureteric stent dwell time from three months to one month was associated with significantly fewer stent-related emergency presentations. Shorter dwell protocols may reduce patient morbidity and healthcare utilisation and could be associated with lower rates of post-ureteroscopy infective complications. Full article

Introduction: Acquired ureteral stricture is an uncommon but clinically relevant complication, mainly associated with long-standing urolithiasis, chronic inflammatory processes, and repeated endourological procedures. Case presentation: We present the case of a 48-year-old woman with left distal ureteral stricture secondary to urolithiasis and repeated endourological procedures, with a complicated clinical course and progressive renal functional impairment. Despite stepwise management including balloon dilations, endoscopic incision, prolonged urinary diversion, and ultimately ureteral reimplantation with a psoas hitch, the patient developed restenosis of the ureteral neomeatus. Due to persistent obstruction, endoscopic dilation with a paclitaxel-coated balloon (Optilume^®) was performed. Subsequent imaging demonstrated partial improvement in ureteral drainage and relative functional improvement of the left kidney. Conclusion: This case highlights the potential complementary role of drug-coated balloons in complex and refractory benign ureteral strictures, although the currently available evidence remains limited.

Background and Clinical Significance: Retroperitoneal urinomas are uncommon complications that can arise following trauma, particularly in the context of congenital anomalies such as pyeloureteral duplication. These conditions pose significant diagnostic and therapeutic challenges, requiring a comprehensive and multidisciplinary approach to ensure optimal patient outcomes. Case Presentation: Here, we report the case of a 22-year-old male who presented to the emergency department with right lumbar and flank pain, nausea, and abrasions following a fall from a height. Initial imaging revealed a right-sided retroperitoneal urinoma and a rare congenital anomaly: complete pyeloureteral duplication with the upper pole draining into the right seminal vesicle. The patient underwent two surgical interventions, including the insertion of a ureteral stent and reimplantation of the ureter using a latero-terminal U trans U technique. Conclusions: This case highlights the complexity of managing traumatic retroperitoneal urinomas associated with congenital anomalies such as complete pyeloureteral duplication. It emphasizes the importance of timely surgical intervention to prevent complications and improve patient outcomes. Full article

Objectives: Real-world data on surgical and multimodal management of upper tract urothelial carcinoma (UTUC) are limited. This study examined epidemiological trends, nephron-sparing surgery adoption, and the perioperative impact of lymphadenectomy (LND) and neoadjuvant chemotherapy (NAC). Methods: The German Nationwide Inpatient Data (GRAND) registry (2005–2023) identified UTUC patients undergoing radical nephroureterectomy (RNU), endoscopic laser destruction, or segmental ureteral resection (SUR) using OPS codes. Demographics, comorbidities, complications, and in-hospital mortality were extracted from ICD-10-GM data. Multivariable regression adjusted for baseline comorbidities assessed associations between treatment type, LND, NAC, and perioperative outcomes. Results: Among 53,427 UTUC patients, 77.3% underwent RNU, 13.8% endoscopic laser destruction, and 8.9% SUR. Endoscopic laser use rose from <10% (2005) to about 20% (2023). LND was performed in 13% of RNU cases, increasing from 1.1% to 19%. LND was associated with higher risks of transfusion (OR 1.47, 95% CI 1.37–1.57), acute kidney injury (OR 1.19, 95% CI 1.07–1.32), and ICU admission (OR 1.21, 95% CI 1.13–1.30), without affecting in-hospital mortality. NAC was given to 1.7% of patients, with a five-fold increase over time, and was associated with more transfusions (OR 1.28, 95% CI 1.07–1.52) and urinomas (OR 2.31, 95% CI 1.31–3.78), but not mortality. Conclusions: UTUC management is evolving, with growing use of endoscopic laser therapy and guideline-aligned lymphadenectomy during nephroureterectomy. Neoadjuvant chemotherapy remains underused despite acceptable perioperative safety, highlighting the need for increased awareness to optimize multimodal treatment. Full article

Background and Objectives: Ureteral access sheaths (UASs) are widely used in retrograde intrarenal surgery (RIRS) to facilitate irrigation and instrument access. Recently, flexible and navigable suction UASs (FANS-UASs) have been developed to enhance visibility and stone fragment evacuation; however, their comparative effectiveness remains uncertain. This study aimed to evaluate the clinical outcomes of FANS-UAS versus conventional UAS during RIRS for renal stones. Materials and Methods: A systematic review and meta-analysis were performed following PRISMA guidelines. PubMed, Embase, and the Cochrane Library were searched through May 2025 for comparative studies of FANS-UAS and conventional UAS. Study quality was assessed using the Scottish Intercollegiate Guidelines Network checklist. Primary outcomes included stone-free rate (SFR), operative time, complications, and hospital stay. Subgroup analyses were conducted according to stone size (≤2 cm vs. >2 cm). Results: Nine studies involving 1791 patients were included. FANS-UAS demonstrated a significantly higher SFR (OR = 5.99, 95% CI: 2.86–12.51; I² = 86.7%) and fewer complications (OR = 0.33, 95% CI: 0.23–0.45; I² = 0%). Operative time and hospital stay did not differ significantly between groups. Subgroup analysis showed no significant SFR difference for stones ≤2 cm, whereas for stones >2 cm, FANS-UAS tended to yield higher SFR—though based on limited evidence. Conclusions: FANS-UASs appear to improve stone clearance and reduce perioperative complications in RIRS without increasing operative burden. While further high-quality randomized trials are needed, current evidence supports the growing adoption of FANS-UAS in endourological practice. Full article
