Background: Testicular Germ Cell Tumors (TGCTs) represent the most frequent malignant tumour among young male adults. Orchiectomy alone cure 80% of stage I. Standard options after orchiectomy include radiotherapy (RT), chemotherapy (CT) by 1 cycle of carboplatin AUC 7 or active surveillance (SV) for seminomatous GCTs (SGCT) and retroperitoneal lymphadenectomy (RPLND), CT by 1 or 2 cycles of Bleomycine Etoposide Cisplatine (BEP) or active surveillance for nonseminomatous GCTs (NSGCT). Adjuvant treatments decrease the relapse rate after orchiectomy with substantial toxicities without any benefit on overall survival. Recent guidelines accorded utmost importance on SV rather than adjuvants strategies. The main objective of this study was to describe our current practice over the 10 past years in regard of these recommendations.

Methods: Data of 50 patients with stage I GCT treated in our institute were collected between 2006 and 2016. Demographic and anatomopathologic data were reported. Clinical practice in our center was analyzed during two periods [2006-2011] and [2012-2016] according to the European Association of Urology Guidelines in 2011.

Results: Patient's median age was 35.3 years. The analysis of clinical practice during the last 10 years showed that in SGCT, main treatment was RT than SV and CT. This option declined over the years (89% between 2006-2010 versus 53% between 2011-2016) whereas SV was more often employed (27% between 2011-2016 versus none between 2006-2010). Surveillance was used for 64% of NSGCT.

Conclusions: In our center, RT was less used over the years for the benefit of SV which is recommended by guidelines.

Ureterorenoscopy with holmium-yttrium-aluminum-garnet fragmentation is a safe and efficient technique for stone treatment in patients with a body mass index superior to 30 kg/m2.

Purpose: The aim of the study was to analyze results and morbidity after flexible ureterorenoscopy in patients with a body mass index (BMI) >30 kg/m(2) and to compare with results obtained in a large cohort of nonobese patients.

Patients And Methods: We conducted a retrospective study including all flexible ureterorenoscopy performed for stone retrieval in our institution between January 2004 and December 2008. During the study period, 224 procedures were performed, of which 18 had to be excluded because of missing BMI data. Thus, a total of 206 procedures were included in the final analysis (34 in 29 obese patients, 172 in 149 nonobese patients). Characteristics of the patients (age, BMI, previous treatment), stones (nature, location, number), and procedures (operating time, morbidity, outcome) were analyzed. Success was defined as clear imaging (completely stone free) on renal tomography and ultrasonography at 1, 3, and 6 months follow-up.

Results: Mean BMI was 34±0.6 kg/m(2) in obese patients (OP) and 24±0.2 kg/m(2) in nonobese patients (NOP). Mean stone size, location, and composition were not significantly different between groups. Operative time was also similar in OP and NOP (102.5±6.1 min vs 103±3.4 min, P=NS). The rate of minor complications (fever, hematuria, flank pain) was similar in OP (11.8%) and NOP (11.4%). No major complication necessitating prolonged hospital stay or new surgical procedure was observed. The overall stone-free rate was not significantly different between OP (79.4%) and NOP (70%).

Conclusion: Flexible ureterorenoscopy is an appropriate treatment for use in obese patients and achieves excellent stone-free rates with low morbidity.
