Objectives: Information on the prediction of improved semen parameters following varicocelectomy is scarce and mostly contradictory. Therefore, we developed and validated a nomogram to predict whether abnormal semen parameters in infertile men could improve following microscopic varicocelectomy (MSV). Methods: From January 2018 to December 2021, 460 consecutive patients who underwent MSV were included. Of them, 336 patients as a development cohort at the Xiang Hua institution. As a validation cohort, Hu Nan Center (124 patients) was used. Clinicopathologic patient information was recorded. The likelihood ratio test using Akaike’s information criteria was employed as the stopping rule, and multivariate logistic regression was utilized to create a prediction model with regression coefficients. The effectiveness of this prediction model was evaluated based on its ability of discrimination, calibration, and clinical utility. Results: The initial total progressively motile sperm count (TPMSC) and vein diameter were predictors of this model. The model demonstrated strong discrimination for the validation cohort, with an area under the receiver operating characteristic (AUROC) of 0.925 (p < 0.001), and strong calibration (unreliability test, p = 0.522). The decision curve study proved the model’s clinical applicability. Conclusion: According to our research, the improvement of semen parameters in infertile men following MSV was significantly predicted by greater vein diameter and higher initial TPMSC. This nomogram aids in individualized decision-making on the varicocele preoperative treatment plan and may help to enhance the therapeutic result. Full article

It is unclear whether local anesthesia (LA) is a viable and safe alternative to general anesthesia (GA) or spinal anesthesia (SA) for microscopic varicocelectomy. As a result, we designed a prospective trial to compare the pain relief, complications, and cost of LA with GA or SA in subinguinal microscopic varicocelectomy (MSV), using the propensity score matching method (PSM). This prospective study was conducted in a tertiary hospital from February 2021 to April 2022. Patients who underwent subinguinal MSV for varicocele were enrolled. The perioperative visual analog scale (VAS) scores, anesthesia-associated side effects, and cost data were recorded, and PSM analysis was performed. Finally, 354 patients were included, of whom 61.0% (216) were treated with LA, and 39.0% (138) underwent GA or LA. After PSM, the patients in the LA group exhibited lower VAS scores both three hours and one day after surgery, and a lower incidence of postoperative analgesic requirement; a lower ratio of patients who experienced anesthesia-associated side effects was also observed in the LA group, compared with the GA or SA group (all p < 0.001). The rate of perioperative satisfaction for patients was higher, the hospital stays and days to return to normal activity were shorter, and the cost was less in the LA group than in the patients in the GA or SA group (all p < 0.001). This prospective PSM cohort demonstrated that LA has the advantages of perioperative pain relief, reduced anesthesia-associated side effects, and cost, compared with GA or SA. It indicated that LA is an effective and safe technique for subinguinal MSV, and may guide clinical practice. Full article
