Evaluation of oncological outcomes of robotic partial nephrectomy according to the type of hilar control approach (On-clamp vs Off-clamp), a multicentric study of the French network of research on kidney cancer-UROCCR 58-NCT03293563.

PURPOSE: To compare off-clamp vs on-clamp robotic partial nephrectomy (RPN) for renal cell carcinoma (RCC) in terms of oncological outcomes, and to assess the impact of surgical experience (SE). METHODS: We extracted data of a contemporary cohort of 1359 patients from the prospectively maintained database of the French national network of research on kidney cancer (UROCCR). The primary objective was to assess the positive surgical margin (PSM) rate. We also evaluated the oncological outcomes regardless of the surgical experience (SE) by dividing patients into three groups of SE as a secondary endpoints. SE was defined by the caseload of RPN per surgeon per year. For the continuous variables, we used Mann-Whitney and Student tests. We assessed survival analysis according to hilar control approach by Kaplan-Meier curves with log rank tests. A logistic regression multivariate analysis was used to evaluate the independent factors of PSM. RESULTS: Outcomes of 224 off-clamp RPN for RCC were compared to 1135 on-clamp RPN. PSM rate was not statistically different, with 5.6% in the off-clamp group, and 11% in the on-clamp group (p = 0.1). When assessing survival analysis for overall survival (OS), local recurrence-free survival (LR), and metastasis-free survival (MFS) according to hilar clamping approach, there were no statistically significant differences between the two groups with p value log rank = 0.2, 0.8, 0.1, respectively. In multivariate analysis assessing SE, hilar control approach, hospital volume (HV), RENAL score, gender, Age, ECOG, EBL, BMI, and indication of NSS, age at surgery was associated with PSM (odds ratio [OR] 1.03 (95% CI 1.00-1.04), 0.02), whereas SE, HV, and type of hilar control approach were not predictive factors of PSM. CONCLUSION: Hilar control approach seems to have no impact on PSM of RPN for RCC. Our findings were consistent with randomized trials.

[Multiple stones of the prostatic urethra associated with anejaculation revealing spinal dysraphism such as tethered cord syndrome at the base of the spinal canal in a young man: about an exceptional case]. / Multiples lithiases de l'urètre prostatique associées à une anéjaculation révélant un dysraphisme spinal à type de syndrome de moelle bas attachée chez un jeune homme: à propos d'un cas exceptionnel.

Spinal dysraphism (or spina bifida) is a neurological disorder representing the first cause of congenital urological disability. It has several clinical manifestations, vesicosphincteric and sexual disorders are frequent and rarely isolated, belonging to motor disorders, orthopedic, sensory, digestive or even cognitive impairments. Tethered cord syndrome at the base of the spinal canal is a complication of spinal dysraphism. This disorder is often detected in children, may be asymptomatic and found in adults. Bladder sphincter disorders are the main cause of morbi-mortality due to uronephrologic complications with a significant alteration in quality of life. This justifies specific management and multidisciplinary and strict monitoring. We here report an exceptional case of spinal dysraphism such as tethered cord syndrome at the base of the spinal canal found incidentally in an adult patient during an etiological assessment of lithiasis of the prostatic urethra associated with anejaculation .

[Neglected scrotal trauma revealing embryonic paratesticular rhabdomyosarcoma: about a case]. / Un traumatisme scrotal négligé révélant un rhabdomyosarcome embryonnaire para-testiculaire: à propos d'un cas.

Embryonic paratesticular rhabdomyosarcoma is a rare mesenchymal tumor constituting a diagnostic and therapeutic emergency. Localized forms have a favorable prognosis. Multimodal treatment is the gold standard and it is based on surgery, multidrug chemotherapy and radiotherapy, with excellent overall survival rate. We here report the case of a 17-year old patient treated in our Department for embryonic fusiform cell paratesticular rhabdomyosarcoma causing clinical confusion. This study aims to highlight the specific features of this disease.
