RÉSUMÉ
Interdisciplinary managed case of a 29-Year-old patient with massive condylomas of the vulva and papillary squamous cell metaplasia of the bladder, leads after years of chronic cystitis and obstruction with meatus plastic and laser treatment to cystectomy with conduit and partial vulvectomy. After long lasting HPV infection with condyloma we also found a squamous cell carcinoma (pT1 G1) of the vulva.

Background: Robot-assisted partial nephrectomy (RAPN) is a challenging procedure that is influenced by a multitude of factors. Objective: To assess the impact of prior surgical experience on perioperative outcomes in RAPN. Design setting and participants: In this retrospective multicenter study, results for 2548 RAPNs performed by 25 surgeons at eight robotic referral centers were analyzed. Perioperative data for all consecutive RAPNs from the start of each individual surgeon's experience were collected, as well as the number of prior open or laparoscopic kidney surgeries, pelvic surgeries (open, laparoscopic, robotic), and other robotic interventions. Intervention: Transperitoneal or retroperitoneal RAPN. Outcome measurements and statistical analysis: The impact of prior surgical experience on operative time, warm ischemia time (WIT), major complications, and margin, ischemia, complication (MIC) score (negative surgical margins, WIT ≤20 min, no major complications) was assessed via univariate and multivariable regression analyses accounting for age, gender, body mass index (BMI), American Society of Anesthesiologists score, PADUA score, and RAPN experience. Results and limitations: BMI, PADUA score, and surgical experience in RAPN had a strong impact on perioperative outcomes. A plateau effect for the learning curve was not observed. Prior laparoscopic kidney surgery significantly reduced the operative time (pâ¯<â¯0.001) and WIT (pâ¯<â¯0.001) and improved the MIC rate (pâ¯=â¯0.022). A greater number of prior robotic pelvic interventions decreased WIT (pâ¯=â¯0.011) and the rate of major complications (pâ¯<â¯0.001) and increased the MIC rate (pâ¯=â¯0.011), while prior experience in open kidney surgery did not. One limitation is the short-term follow-up. Conclusions: Mastering of RAPN is an ongoing learning process. However, prior experience in laparoscopic kidney and robot-assisted pelvic surgery seems to improve perioperative outcomes for surgeons when starting with RAPN, while experience in open surgery might not be crucial. Patient summary: In this multicenter analysis, we found that a high degree of experience in keyhole kidney surgery and robot-assisted pelvic surgery helps surgeons in achieving good initial outcomes when starting robot-assisted kidney surgery.
RÉSUMÉ
The standard diagnostic and follow-up examination for bladder cancer is diagnostic cystoscopy, an invasive test that requires compliance for a long period. Urine cytology and recent biomarkers come short of replacing cystoscopy. Urine liquid biopsy promises to solve this problem and potentially allows early detection, evaluation of treatment efficacy, and surveillance. A previous study reached 52-68% sensitivity using small-panel sequencing but could increase sensitivity to 68-83% by adding aneuploidy and promoter mutation detection. Here, we explore whether a large 127-gene panel alone is sufficient to detect tumor mutations in urine from bladder cancer patients. We recruited twelve bladder cancer patients, obtained preoperative and postoperative urine samples, and successfully analyzed samples from eleven patients. In ten patients, we found at least one mutation in bladder-cancer-associated genes, i.e., a promising sensitivity of 91%. In total, we identified 114 variants, of which 90 were predicted as nonbenign, 30% were associated with cancer, and 13% were actionable according to the CIViC database. Sanger sequencing of the patients' formalin-fixed, paraffin-embedded (FFPE) tumor tissues confirmed the findings. We concluded that incorporating urine liquid biopsy is a promising strategy in the management of bladder cancer patients.
RÉSUMÉ
Preputioplasty denotes various surgical techniques directed at resolving phimosis without the need for radical or partial circumcision. This narrative review summarizes the best-known surgical techniques of preputioplasty. A MEDLINE and EMBASE-based literature search of original manuscripts and case reports published in English has been carried out using the following key words: "circumcision", "partial circumcision", "phimosis", "paraphimosis", and "preputioplasty". Six different procedures are explored in more detail and illustrated. The complication rates of all surgical procedures presented here are reported to be low. In cases of medical (rather than cultural and religious) indications, foreskin-preserving procedures present useful alternatives to circumcision in the routine clinical practice of urologists and pediatric surgeons.

OBJECTIVE: Comparison of the retroperitoneal (RRPN) perioperative variables and the transperitoneal (TRPN) robot-assisted partial nephrectomy (RPN) using a matched-pair analysis. MATERIAL AND METHODS: A retrospective review was carried out for 224 patients who underwent RPN between 2014 and 2019. A matched-pair analysis was performed on 51 pairs of patients. The matching criteria were age, Charlson comorbidity index, body mass index, the grade of renal insufficiency, tumor diameter, and Preoperative Aspects and Dimensions Used for an Anatomical Classification of Renal Tumors score. RESULTS: The time to reach the renal hilum (P < .001), the overall complication rate (P » .008), and the major complication rate (P » .01) were lower in the RRPN group. The operative time was 143 vs 150minutes (P » .63) in RRPN vs TRPN, respectively. Warm ischemia time was 10minutes in RRPN vs 12minutes in TRPN (P » .07). Early unclamping was used in 71% in RRPN vs 48% in TRPN (P » .02). The length of hospital stay was 6 days in both groups (P » .11). The cases' complexity, the rate of positive surgical margins, and postoperative kidney function were comparable in both groups (P > .05). CONCLUSION: The advantages of RRPN lie in the shorter time to reach the renal hilum and the lower complication rates; the comparability with the other parameters proves the safety and feasibility of the RRPN access for localized kidney tumors.

BACKGROUND: With increasing acceptance of robotic partial nephrectomy over the last decade, there is an ongoing discussion about the transperitoneal versus retroperitoneal access. OBJECTIVE: To report outcomes after transperitoneal (TRPN) versus retroperitoneal (RRPN) robotic partial nephrectomy. DESIGN, SETTING, AND PARTICIPANTS: A total of 754 patients were identified from the databases of three high-volume centers who underwent either TRPN (n = 551) or RRPN (n = 203). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Perioperative data were evaluated retrospectively. A propensity score matched-pair analysis was performed with the following variables: grade of renal insufficiency, age, body mass index, tumor diameter, and preoperative aspects and dimensions used for an anatomical (PADUA) score with a subsequent subgroup analysis for tumor location. For quality outcomes, the margin, ischemia, and complications (MIC) criteria were used (negative margins, ischemia time <20 min, and no major complications). Statistical analyses included chi-square and Mann-Whitney U tests. RESULTS AND LIMITATIONS: In all, 176 patients could be matched in each group. The median tumor diameter was 28 mm with a PADUA score of 9. In 11% of RRPN versus 44% of TRPN cases, an anterior tumor location was found, and in 55% versus 30%, a posterior lesion was found (p < 0.001). Operative time (119 vs 139 min, p < 0.001) and warm ischemia time (9 vs 10 min, p = 0.003) were significantly shorter for RRPN. No significant differences were observed between intra- and postoperative complication rates, with 8% major complications in TRPN versus 3% in RRPN (p = 0.06). The MIC criteria were achieved in 90% in the RRPN versus 88% in the TRPN group, without differences for tumor location. CONCLUSIONS: Significant differences between TRPN and RRPN could be found for intraoperative time, while complication rates and quality outcomes were comparable. RRPN can also be a considerable alternative for anterior tumors. PATIENT SUMMARY: In this study, we demonstrate that robotic partial nephrectomy is feasible with either a transperitoneal or a retroperitoneal surgical access. The posterior approach can also be used for anterior renal tumors and may result in shorter operative time.

BACKGROUND: Peyronie's disease (PD) can be a cosmetically and functionally devastating condition. Surgical approaches have been proposed in the chronic stages of PD as plication or plaque incision/excision with grafting to preserve penile size in complex cases. Although several surgeons nowadays are inclined toward the utilization of non-autologous grafts owing to the ease of their preparation and availability, synthetic graft procedures still await more technical improvements and supporting evidence before their consideration for standard care. OBJECTIVES: In this review, our goal is to facilitate an insight into the most promising grafting materials used for the management of PD and techniques associated. MATERIALS AND METHODS: A PubMed review was conducted for all the studies on our topic within the past ten years (January 2009 until December 2019). The outcome parameters we documented and compared comprised of operative time, follow-up time, postoperative penile cosmesis and function, and, finally, overall patient satisfaction related to each technique. RESULTS: Our search yielded 23 English-written original study articles in addition to a single case report on the various grafting techniques utilized as the sole treatment for PD, each demonstrating different outcomes and points of comparison. CONCLUSION: A successful grafting procedure for PD requires an appropriately tailored surgical modality and an experienced surgeon. Nevertheless, proper preoperative patient counseling on all aspects of his condition and opted treatment modality while setting clear and realistic expectations remains key for overall patient satisfaction.

PURPOSE: To identify the role of Doppler US (DUS) in the prediction of factors affecting stone-clearance post-SWL for ureteral stones in addition to its role in prediction of pretreatment stone impaction. METHODS: We prospectively included patients with ureteric stone for SWL between October 2018 and September 2019. Patient's demographics were collected. Using DUS, resistive index (RI), Δ RI, and ureteric jets were evaluated in both kidneys. Also, stone site, volume, density, skin to stone distance, degree of hydronephrosis, ureteral wall thickness (UWT) were evaluated by NCCT. Univariate and multivariate logistic regression analyses were performed to identify factors that contribute to treatment success. Correlation between ipsilateral RI with other radiological findings predicting stone impaction was done. RESULTS: A total of 93 patients were finally included (61 males and 32 females). The mean age was 31.4 ± 7.7 years. The success rate (absence of significant residuals post 1 month by NCCT) was 51.6%. In multivariate analysis, the presence of ureteric jet, ipsilateral lower RI, and ipsilateral lower UWT were independent factors for treatment success (P = 0.0001, 0.002, and 0.03, respectively). Also, ipsilateral absence of ureteric jet, increased hydronephrosis, and increased UWT were correlated with higher ipsilateral RI in prediction of stone impaction. Ipsilateral higher RI was found to achieve higher accuracy in stone impaction prediction (PPV of 94.8%). CONCLUSION: Pretreatment DUS is a useful, non-invasive with a less irradiative tool for prediction of stone impaction and stone-free rate post-SWL for ureteric stones.

PURPOSE: To evaluate the efficacy of oral dissolution therapy (ODT), shock wave lithotripsy (SWL), and combined SWL and ODT for medium-sized radiolucent renal stone (RLS). METHODS: A randomized controlled trial for patients with medium-sized RLS, 1-2.5 cm, ≤ 500 Hounsfield unit (HU). The ODT patients were counseled for oral potassiumsodium-hydrogen citrate (Uralyt-U®). The 2nd group underwent SWL and the last group had combined SWL and ODT. The primary outcome, stone-free rate (SFR) at 3 months, was assessed by non-contrast computed tomography (NCCT). We defined complete response (success) if no residual fragment were detected by NCCT; partial response (failure) if there was a decrease in stone size, but presence of residual stones; no response if there was no change or increase in stone size (failure). RESULTS: 150 patients completed follow-up. The SFR at 1st month and 3rd month were, respectively; 16% and 50% in the ODT group, 10% and 46% in the SWL group, and 35% and 72% patients in combined group with (p = 0.03 and 0.003, respectively. The overall SFR for all groups was 66%. Combined treatment and initial response in first month follow-up were independent factors predicting SFR. In addition, combined treatment significantly decreased the overall stone volume (p = 0.03) and the need for additional stone management procedures after 3 months (p = 0.01). CONCLUSION: Combined ODT and SWL treatment constitutes the most rapid and effective therapeutic approach for medium-sized RLS, decreasing overall stone volume as well as the number of SWL sessions needed in comparison to SWL therapy, alone.

Chronic hepatitis C is implicated in insulin resistance (IR) susceptibility. An X-ray repair cross-complementing group 1 gene (XRCC1) is proposed to be a candidate gene for a study of IR susceptibility. So, this study aims to investigate the possible association of the XRCC1 gene polymorphisms with the risk of IR related to chronic hepatitis C virus (HCV) infection in Egyptian patients. In a case-control study, a total of 210 subjects, including 140 chronic HCV patients (87 patients with IR and 53 without IR) and 70 healthy controls, were included. Two genetic polymorphisms (c.1254C > T and c.1517G > C) of the XRCC1 gene were genotyped via the PCR-restriction fragment length polymorphism (PCR-RFLP) technique. The result of the current study revealed that these two single nucleotide polymorphisms (SNPs) have statistically significant influences on susceptibility to IR in chronic HCV infected Egyptian patients. It could be concluded that c.1254C > T, the TT genotype, CT/CC carriers as well as c.1517G > C, the CC genotype and GC/GG carriers might be associated with increased IR susceptibility. Moreover, T-allele of c.1254C > T and the C-allele of c.1517G > C genetic variants might influence the susceptibility.
