Background: The role of kidney-sparing surgery in patients with high-risk upper urinary tract urothelial carcinoma is controversial. The present study aimed to assess oncological and functional outcomes of robot-assisted distal ureterectomy in patients with high-risk distal ureteral tumors.

Methods: The ROBUUST 2.0 multicenter international (2015-2022) dataset was used for this retrospective cohort analysis. High-risk patients with distal ureteral tumors were divided based on type of surgery: robot-assisted distal ureterectomy or robot-assisted nephroureterectomy. A survival analysis was performed for local recurrence-free survival, distant metastasis-free survival, and overall survival. After adjusting for clinical features of the high-risk prognostic group, Cox proportional hazard model was plotted to evaluate significant predictors of time-to-event outcomes.

Results: Overall, 477 patients were retrieved, of which 58 received robot-assisted distal ureterectomy and 419 robot-assisted nephroureterectomy, respectively, with a mean (±SD) follow-up of 29.6 months (±2.6). The two groups were comparable in terms of baseline features. At survival analysis, no significant difference was observed in terms of recurrence-free survival (P=0.6), metastasis-free survival (P=0.5) and overall survival (P=0.7) between robot-assisted distal ureterectomy and robot-assisted nephroureterectomy. At Cox regression analysis, type of surgery was never a significant predictor of worse oncological outcomes. At last follow-up patients undergoing robot-assisted distal ureterectomy had significantly better postoperative renal function.

Conclusions: Comparable outcomes in terms of recurrence-free survival, metastasis-free survival, and overall survival between robot-assisted distal ureterectomy and robot-assisted nephroureterectomy patients, and better postoperative renal function preservation in the former group were observed. Kidney-sparing surgery should be considered as a potential option for selected patients with high-risk distal ureteral UTUC.

Background: The aim of this study was to investigate the efficacy, safety, and outcomes of the combination of low ıntensity external shock wave therapy (Li-ESWT) and platelet-rich plasma (PRP) therapy in acute phase Peyronie's disease (PD).

Methods: The datas of patients admitted with acute phase Peyronie's between January 2014 and January 2022 were reviewed retrospectively. In total, we included total 159 patients who used combination of vitamin E 600 mg/day plus colchicine 1.5 mg/day plus oral daily 5 mg tadalafil (N.=77) in group 1 and received Li-ESWT+PRP combination therapy plus oral daily 5 mg tadalafil (N.=82) in group 2. We noted characteristics of fibrous plaques, pain status, penile curvature degree, and erectile function parameters. All patients were visited at the 3^rd and 12^th months after the treatment.

Results: Preoperative demographic characteristics were similar in the two groups. There was a statistically significant improvement in the mean plaque size, penile curvature degree, IIEF-5 and VAS scores in the intervention group after the treatment. Ecchymosis and hematoma were not observed at the injection site and Li-ESWT application areas in the intervention group. No local or systemic drug reactions were noted in either group.

Conclusions: Combination of Li-ESWT and PRP are highly effective and safety to early treatment in the acute phase PD.

Introduction: Consensus for Enhanced Recovery After Surgery (ERAS) in pediatrics has been achieved in neonatal intestinal surgery, yet it is not widely utilized in pediatric urology. We investigated the application of ERAS guidelines in pediatric urology, and determined its effects given the available level of evidence supporting the ERAS protocol in children.

Evidence acquisition: A systematic literature review including series providing adoption of fast-track recovery protocols for pediatric urology procedures was carried out. Main outcome measures were study characteristics, adherence to the 19 ERAS items, complication rates and length of hospital stay. Sub-group analysis by surgery type (hypospadias versus major surgery) was performed.

Evidence synthesis: Nine series with data from 1272 surgical pediatric cases were included. An enhanced recovery pathway was applied in 67.3% of the reports. Two series included patients undergoing hypospadias repair and ERAS items were insufficiently reported. Studies including children undergoing major procedures mentioned a median of 15 ERAS items, yet applied a median of 11 items. Median compliance rate was 88.9% (range 50-100). More ERAS guideline items were reported (applied or mentioned) in the most recently published studies.

Conclusions: There is limited reporting and use of the ERAS guidelines in urologic surgery particularly in hypospadias repair; whilst in major surgery in children, adherence and compliance rates vary widely. In more recent series there was an increase in ERAS items that have been mentioned and applied. Future research is needed to identify barriers and to overcome them in order to fully adopt and benefit from the ERAS pathway.

Introduction: Inguinal lymph nodes dissection (ILND) is recommended in patients presenting with high-risk penile (PC) or vulvar cancers (VC). Though, this surgical procedure is underused because of its anticipated morbidity. Minimally invasive approaches were proposed to minimize complications associated with open surgery. In this review, we analyze current available data exploring intra and perioperative outcomes of robot-assisted ILND (RAIL).

Evidence acquisition: On April 9^th, 2023, a literature search was conducted using the PubMed and Scopus databases. The search employed the combination of the following terms: ("robotic assisted" OR "robot-assisted" OR "robotic") AND ("inguinal lymph node dissection" OR "lymphadenectomy") AND ("penile cancer" OR "vulvar cancer"). Out of the 404 identified articles, 18 were used for the present scoping review and their results were reported according to the PRISMA statement.

Evidence synthesis: Data on 171 patients, ranging in age from 32 to 85 years, were obtained. Most of them (90.6%) harbored a penile squamous cell carcinoma and presented with no palpable nodes (85%). Operation time (OT) ranged between 45 and 300 min. Estimated blood loss varied from 10 to 300 mL. One single intra-operative complication was reported and one conversion to open was recorded. The lymph nodes (LNs) count spanned from 3 to 26 per groin, with 17 studies reporting a median yield >7 nodes. Hospital stay was 1-7 days, while the duration of drainage ranged from 4 to 72 days. Post-operative complications included lymphocele (22.2%; 0-100%), lymphedema (13.4%; 0-40%), cellulitis (11.1%; 0-25%), skin necrosis (8.7%; 0-15.4%). seroma (3.5%; 0-20%) and wound breakdown/wound infection (2.9%; 0-10%). Out of the included studies, 7 provided at least a 12-month follow-up, with recurrence-free rates ranging from 50% to 100% in patients affected by penile cancer and from 92% to 100% in vulvar cancer patients.

Conclusions: The available evidence on RAIL for the treatment of PC and VC is limited. The approach appears to be safe and effective, as it provides an adequate lymph node yield while ensuring a minimally morbid postoperative course and a short hospital stay.

Background: The objective of this retrospective, multicenter study was to analyze the factors associated with the development of urogenital sepsis after percutaneous nephrolithotomy (PCNL) and to establish a nomogram prediction model of urogenital sepsis after PCNL.

Methods: A total of 2066 postoperative PCNL patients were included from three medical institutions: Zunyi Medical University Hospital, Beijing Jishuitan Hospital Guizhou Hospital, and Fenggang County People's Hospital. Clinical data of 1623 patients from the Department of Urology of Zunyi Medical University Hospital were randomized into a training cohort (Zunyi training cohort, N.=1139) and an internal validation cohort (Zunyi internal validation cohort, N.=484) using computer generated random numbers in a 7:3 ratio. Univariate and multivariate logistic regression analyses were performed on the compliance training cohort to identify risk factors for urogenital sepsis after PCNL and to develop a column line graph prediction model based on these risk factors. Finally, Zunyi internal validation cohort and two external validation cohorts (Guiyang external cohort, N.=306; Fenggang external cohort, N.=137) were used to validate the prognostic accuracy of the nomogram prediction model. R4.2.2 statistical software was used for all statistical data analyses.

Results: Multifactorial logistic regression analysis of the Zuiyi training cohort (N.=1139) identified five independent risk factors associated with urogenital sepsis after PCNL, including urine culture positivity (odds ratio [OR]=5.29, P<0.001), urine nitrite positivity (OR=5.97, P<0.001), operation time ≥60 min (OR=4.4, P=0.0037), residual stone (OR=5.18, P<0.001), and size ≥30 mm (OR=3.22, P=0.0086). Nomogram were constructed based on these independent risk factors. The area under the curve (AUC) of the nomogram model was 0.907 in the in-progress sample and 0.948 after internal validation. The AUC of the model was 0.855 and 0.804 after external validation of the Guiyang external validation cohort and the Fenggang validation cohort, respectively, indicating good discrimination ability. The calibration curves of the nomogram showed good agreement, and the decision curve analysis demonstrated high clinical utility.

Conclusions: Based on the clinical independent risk factors such as positive urine culture, positive urine nitrite, operation time ≥60min, stone residue, stone size ≥30mm, nomogram prediction model of urogenital sepsis after PCNL was established, which can provide reference for urologists to develop preoperative evaluation and treatment strategies for patients with percutaneous nephrolithotomy.
