Special Issue Information

Dear Colleagues,

You have probably read about the survey findings of individuals with spinal cord injury and multiple sclerosis where continuing urological problems are reported as their primary concerns. Difficulties encountered include the use of bladder catheters, urinary tract infections, and other urologic morbidities. We all agree that further research is needed to address these concerns; however, there are many hurdles to overcome. This Special Issue of Uro is promoting research in this area by presenting reports as position statements, reviews, and studies. One article being considered for publication is on the use of wireless TENS (transcutaneous electrical stimulation) units to assist SCI and MS patients with bladder inhibition and incontinence management. Another article is on the need to test Urecholine, 50 mg/BID, after a failed decatheterization test to help patients obtain volitional voiding. We hope that further articles will be submitted over the next year. The journal is waving fees for publishing these articles, which will be available as open press on the web. Articles should be submitted at the journal’s website, and all articles will go through external review prior to approval for publication. We also want to mention that the editors of this Special Issue and others are initiating an International Neuro-Urology Research Group to further work in this area. The group is offering assistance in the areas of writing, study design, analysis, and publication, as well as providing limited funding. For further information about this group, our mission, and this Special Issue, contact James Walter, Ph.D., [email protected].

Background: The development of drug resistance among causative agents has resulted in the need to change the paradigm toward alternative therapeutic approaches for uncomplicated urinary tract infections (UTIs). The objective of the present study was to evaluate the efficacy of an oral medical device containing xyloglucan, hibiscus, and propolis in clinical practice with a cohort of women from Switzerland with UTI-like symptoms and the administration of concomitant drugs. Materials and Methods: This work describes an observational, prospective, and multicenter study involving 103 women attending a primary care physician for a symptomatic episode, or recurrence, of acute uncomplicated cystitis between August 2018 and June 2019. Utipro®Plus was administered orally, with patients being prescribed two capsules per day for 5 days to control discomfort symptoms or one capsule per day for 15 consecutive days per month (followed by a 15-day break for a 3-month cycle) to prevent recurrences. Results: A total of 84 women (81.6%) did not require an additional consultation, whereas 17 (16.5%) required a second one. Inadequate treatment response was found in 7 women out of the 19 who required a further consultation (36.8%): 3 women with no history of cystitis (out of 13, 23.1%) and 4 with recurrent cystitis (out of 6, 66.7%). None of the women from the study reported an adverse event. Conclusions: The studied product containing xyloglucan, hibiscus, and propolis is safe and effective for the treatment of a broad spectrum of women with acute uncomplicated or recurrent UTI-like symptoms.

Introduction: Urinary incontinence is a prevalent condition, especially in elderly men, with stress urinary incontinence (SUI) being a common cause after radical prostatectomy. The artificial urinary sphincter (AUS), particularly the AMS 800™ device, has been the gold-standard treatment for moderate-severe male SUI for decades. Despite some technical advancements and alternative devices like ZSI-375, Victo, and BR-SL-AS 904 being introduced, there is limited literature comparing their effectiveness to the AMS 800™. Methods: This literature review compares the AMS 800™ to the newer technologies in the management of SUI. We reviewed the current literature on urinary sphincter implant in male stress incontinence, including AMS 800™, ZSI-375, Victo, and BR-SL-AS 904. Findings: The AMS 800™ is a sophisticated system consisting of an inflatable cuff, a pressure-regulating balloon, and a control pump. Studies show continence rates ranging from 61% to 100% with AMS 800™ implants, with low infection rates and significant improvement in patients’ quality of life. The ZSI-375 sphincter is a unique single-piece cuff without an abdominal reservoir, simplifying implantation. Preliminary data show a social continence rate of 73% at six months, with lower complication rates than the AMS 800™. The VICTO® device offers adjustable pressure and a stress relief mechanism, providing conditional occlusion of the urethra. Early studies report a satisfaction rate of up to 94.2% and a complication rate of 17.6%. BR-SL-AS 904 is a newly proposed urinary sphincter, but due to the limited number of cases and a single study, its efficacy and complication rates remain uncertain. Conclusions: Overall, AMS 800™ remains the gold-standard treatment for SUI after radical prostatectomy. Alternative devices like ZSI-375 and VICTO® show promising results, but longer studies and more data are needed to establish their effectiveness and safety compared with the AMS 800™. Further research and ongoing monitoring are essential to address mechanical issues associated with AUS implants. Full article

Detrusor sphincter dyssynergia (DSD) is defined as an external urethral sphincter anomalous contraction concomitant to detrusor contraction during voiding, due to a neurological disease. It commonly occurs in suprasacral spinal cord-injured (SCI) patients and can be associated with autonomic dysreflexia. DSD generates risks to the urinary system and overall health; hence, it should be promptly diagnosed and managed. Bladder neck dyssynergia is a condition that should be integrated in DSD assessment. We reviewed the literature indexed in PubMed/Medline on the evaluation methods of DSD in SCI patients. Urodynamics is the mainstay evaluation method and has a prognostic value for the progression of upper urinary tract structural degradation and renal function decline. We found a lack of consensus on the optimal urodynamics configuration when evaluating DSD, especially in obtaining and measuring the signal from external urethral sphincter (EUS) activity. It appears that a combination of recordings of voiding cystourethrography and EUS electromyography, either with or without EUS pressure measurement, is the most accurate method available for evaluating DSD. While gathering articles, we came across an interesting approach in evaluating DSD in the past: urodynamics coupled with ultrasound imaging. Despite being considered valuable from a diagnostic standpoint by some prominent authors, it is no longer represented in the current literature. In addition to the instrumental diagnosis, health professionals should consider additional clinical features when evaluating and managing DSD in SCI patients, to design a customized plan to achieve the best compromise between quality of life and urinary system protection.

Introduction: A 51-year-old male was seen complaining of pneumaturia and bowel complaints, including blood per rectum. The patient related a history of an open left inguinal hernia repair utilizing a Kugel mesh ten years before. Case Presentation: Cystoscopy and colonoscopy demonstrated a hemorrhagic mass due to a prosthetic mesh protruding into the bladder and colon. Following colonoscopy and cystoscopy, a large inflammatory mass involving both the colon and urinary bladder was resected, which contained a rolled-up “tubular” mesh structure. After primary repair of the urinary bladder and placement of a Foley catheter, the sigmoid colon and mesh were resected, and the colonic anastomosis was completed. Outcome: Postoperatively, the patient progressed well with normal colon and bladder function after the removal of the Foley catheter. Discussion: Historically, the patient demonstrated the risk of major multiorgan surgical complications of a newer inguinal hernia repair technique, which may occur even a decade or more after the initial surgical correction and is, therefore, presented.

Retroperitoneal tumors are uncommon and may reach a large size prior to causing symptoms or being noticed by the patient or physician. A middle-aged female consulted us for care during her “terminal” illness. She had already undergone four previous retroperitoneal resection surgical procedures. She presented with a large recurrent protruding mass from the right side of the abdomen and related a history of a previous cholecystectomy, right nephrectomy, right colectomy, and repeated resection of a recurrent retroperitoneal liposarcoma. She thus came to us for consultation and terminal care in order to be away from her friends during treatment for this terminal condition. After our consultation, she elected to have repeated surgical excisions of the tumor. The surgical excisions yielded a giant recurrent tumor mass, which overflowed and covered all margins of the 21-inch-wide surgical scrub basin. Over the next eleven years, she had multiple surgical resection procedures involving both the right and left retroperitoneum (a splenectomy, a left colectomy, and a colostomy). Recovery from each of these resection procedures (the final combined resection weight was 120 pounds) was without complications. However, the tumor finally encased the pancreas and the left kidney. If the tumor encasement were to be palliated and resected, she would require hemodialysis. At this time, the patient elected to have no further resection surgeries, no dialysis, nor any palliative chemoradiation treatment. Over a period of sixteen years from her first resection and twelve years from our first resection, the patient had continued to work at her medical administrative and leadership position and led a functional life after our consultation, except for her surgical period. The patient was not cured but benefited from repeated palliative surgeries, prolonging her life and improving her job performance. Full article

Historically, ureteral complications during surgery have been occurring since the earliest performances of major abdominal or pelvic surgery. In the early 1960s, few diagnostic techniques were available to diagnose ureteral injury and determine the subsequent timely treatment required. Illustrations from two different time periods of possible operative ureteral injury, ligation, or transection following major complicated surgical procedures are presented, along with the diagnostic and therapeutic approach currently followed. The first individual had apparently sustained a ureteral injury during a prior surgical procedure, which, with limited diagnostic options, was not recognized until she visited us years later—as was the case for many early ureteral injuries. Major abdominal or pelvic surgery may be extensive and complicated, especially when dense fibrosis, scarring, and benign or malignant mass formation are present. Unfortunately, surgical complications, including bleeding and ureteral concerns, may develop during these extensive procedures. A more recent patient underwent major, life-threatening retroperitoneal surgery due to a chronic aortoenteric fistula (17 months total preoperative hospitalization elsewhere), during which the left ureter was transected. In our second patient, recognition and correction of the ureteral transection during the aortic surgery, upon completion of the aortic repair, prevented a potential major renal complication. The timely diagnosis of the operative ureteral injury and the repair prior to wound closure prevented major postoperative complications. As some physicians believe that surgically induced ureteral injuries are increasing in frequency, we present this report to enhance awareness of the possibility of injury and the potential value of recognition prior to abdominal closure. In addition, current operative and postoperative strategies available to identify and reduce potential ureteral injury complications when they occur are discussed. Full article

Motor vehicle accidents continue to cause thousands of life threatening injuries or mortality (nearly 45,000 deaths in 2021) in the United States. A sixteen year-old young man riding a motorcycle was severely injured when struck by an automobile driven by an individual under the influence of alcohol. Multiple long bone fractures, the left renal artery torn off the aorta, with non-function of the left kidney, urinary bladder rupture with cystourethral injury, thoracic aortic disruption, and splenic fracture injuries were present. Emergency repair of the thoracic aorta, splenectomy, and left renal artery bypass were all completed. Absorbable suture repair of the urinary bladder and cystouretheral junction injuries followed Foley and suprapubic bladder decompression. All long bone fractures were stabilized and corrected. Normal urinary function of the left kidney returned, and urinary bladder control accompanied the four-month recuperation. Six and twelve month follow-up showed almost normal mobility with normal bilateral renal and urinary bladder function. Full article

Spinal cord injury can either be complete with no neural communication across the injury level or incomplete with limited communication. Similarly, motor neuron injuries above the sacral spinal cord are classified as upper motor neuron injuries, while those inside the sacral cord are classified as lower motor neuron injuries. Specifically, we provide recommendations regarding the urological management of complete upper motor neuron spinal cord injuries; however, we also make limited comments related to other injuries. The individual with a complete upper motor neuron injury may encounter five lower urinary tract conditions: first, neurogenic detrusor overactivity causing urinary incontinence; second, neurogenic detrusor underactivity resulting in high post-void residual volumes; third, detrusor sphincter dyssynergia, which is contraction of striated and/or smooth muscle urethral sphincters during detrusor contractions; fourth, urinary tract infection; and fifth, autonomic dysreflexia during detrusor contractions, which produces high blood pressure as well as smooth muscle detrusor sphincter dyssynergia. Intermittent catheterization is the recommended urinary management method because it addresses the five lower urinary tract conditions and has good long-term outcomes. This method uses periodic catheterizations to drain the bladder, but also needs bladder inhibitory interventions to prevent urinary incontinence between catheterizations. Primary limitations associated with this management method include difficulties with the multiple catheterizations, side effects of bladder inhibitory medications, and urinary tract infections. Three suggestions to address these concerns include the use of low-friction catheters, wireless, genital-nerve neuromodulation for bladder inhibition, and consideration of urine egress into the urethra as a risk factor for UTI as well as egress treatment. The second management method is reflex voiding. This program uses external condoms for urine collection in males and diapers for females. Suprapubic tapping is used to promote bladder contractions. This method is not recommended because it has high rates of medical complications. In particular, it is associated with high detrusor pressure, which can lead to ureteral reflux and kidney pathology. Botulinum toxin injection into the urethral striated sphincter can manage detrusor sphincter dyssynergia, reduce voiding pressures, and risks to the kidney. We suggest a modified method for botulinum toxin injections as well as five additional methods to improve reflex voiding outcomes. Finally, the use of intermittent catheterization and reflex voiding for individuals with incomplete spinal injuries, lower motor neuron injuries and multiple scleroses are briefly discussed.

In 50% of typical (nonneurogenic) women, at least one urinary tract infection (UTI) will occur, with cystitis being the most common UTI, with about 25% of patients experiencing recurrence. A factor not currently included in UTI risk models is egress of urine from the bladder into the urethra during bladder filling and activities of daily living. Urinary egress, if it occurs, would shorten the distance that bacteria need to travel to gain access to the bladder. Video urodynamics with contrast medium can demonstrate urinary egress; however, the observations can be difficult to conduct. Egress can be expected to be more likely in women with lower urinary tract conditions such as urge and stress incontinence. Treatment of the incontinence also reduces UTI rates and the reduction could, in part, be due to reduced urine egress. If UTI risk remains after incontinence management, then further treatment with pelvic floor exercises and pessaries could be considered to reduce the risk from potential residual urine egress. In summary, urine egress as a risk factor for UTI needs further research and clinical consideration. Full article
