Bilateral Pedicled Scrotal Flaps as an Alternative to Skin Graft in Penile Shaft Defects Repair.

OBJECTIVE: To analyze surgical and functional outcomes of bilateral pedicled scrotal flaps for penile shaft reconstruction. MATERIALS AND METHODS: A retrospective analysis was performed on 22 patients who underwent penile shaft reconstruction with bilateral pedicled scrotal flaps between 2009 and 2017. Demographics, peri-operative data, and surgical complications were collected. Functional outcomes were analyzed using a questionnaire made of the erection hardness score, the patient and observer scar assessment scale, and a 10-point Likert scale measuring patients... satisfaction about their skin coloration, sensitivity, elasticity and thickness, penile size, scrotal volume, erection quality, penetration ability, pain, sexual satisfaction, body image, masculinity, self-esteem, and global satisfaction. RESULTS: Patients exhibited a wide range of indications, including buried penis (27.2%), or subcutaneous injections of foreign material (27.2%). Early complications were suture dehiscence (31.8%), infection (13.6%) and hematoma (4.6%), associated with 9.1% of surgical revisions. Late complications were skin retraction (27.3%), testicular ascension (22.7%), pyramidal shape (4.6%) or shortening (13.6%) of the penis, associated with 27.3% of surgical revisions. For the 12 patients who answered the questionnaire, median erection hardness score and patient and observer scar assessment scale score [IQR] were 3.5 out of 4 [2.5-4] and 11.5 out of 60 [9.5-22], respectively. The patients reported a positive impact of the surgery on their psychological condition, with a median score of global satisfaction of 8 [IQR 7.5-9.5]. CONCLUSION: Bilateral pedicled scrotal flaps seem.ßto be a safe alternative for shaft defects reconstruction despite a potential need of surgical revision, providing satisfactory functional outcomes.

Safety of dual kidney transplantation compared to single kidney transplantation from expanded criteria donors: a single center cohort study of 39 recipients.

Our objective was to compare the outcomes of dual kidney transplanataion (DKT) to single kidney transplantation (SKT) performed with grafts from expanded criteria donors (ECD) in recipients ≥65 years, focusing on surgical complications. All kidney transplantations (KT) performed between 2006 and 2014 in our institution were analysed. DKT was indicated according to the criteria of the French national Agence de la Biomedecine. Thirty-nine DKT and 155 SKT were included, with a median follow-up of 36 and 26.5 months, respectively. The rate of early surgical revisions was not significantly higher after DKT (23.1% vs 15.5% (P = 0.2593)) but more venous graft thromboses (12.8% vs 3.2% (P = 0.02)) were reported. The glomerular filtration rate (GFR) 24 months after KT was significantly higher after DKT (45.0 ± 16.3 vs 39.8 ± 13.8 ml/min/1.73m2 ; P = 0.04) and allowed shorter waiting time without a significant increased risk of surgical revision, excepted for venous graft thrombosis, more frequent after DKT. Graft survivals were not significantly different and GFR was higher after DKT. DKT seems to remain an appropriate strategy to address the growing graft shortage in elderly patients.

Comprehensive study of three novel cases of TFEB-amplified renal cell carcinoma and review of the literature: Evidence for a specific entity with poor outcome.

The first case of TFEB-amplified renal cell carcinoma was published in 2014. Since then, 29 additional cases have been described. The prognostic and therapeutic implications of this rare entity remain to be determined. We describe here the clinical, histological, and genetic features of three novel cases, and the first complete literature review. Four tumors were examined from three patients selected from the large collection of genetically characterized renal tumors in our institution. The pathological and immunohistochemical features were centrally reviewed by a uropathologist. Quantitative and structural genomic abnormalities were analyzed using comparative genomic hybridization, fluorescence in situ hybridization, and next generation sequencing. The three cases showed high-level amplification but no translocation of TFEB. Histologically, two tumors showed a papillary or pseudopapillary architecture. They did not show similarities with renal cell carcinoma harboring translocation of TFEB. The tumors were locally advanced high-grade lesions. They exhibited a metastatic course, which was rapidly leading to death in one patient. A second patient developed metastatic disease that did not respond to four lines of targeted treatments. The third patient had a protracted history of pulmonary and cardiac metastases. Complete clinical and biological data were examined and compared to those of the reported cases. Within the classification of renal tumors, TFEB-amplified renal cell carcinoma may constitute a novel entity characterized histologically by high-grade, papillary or pseudopapillary architecture, and necrotic remodeling and clinically by a poor outcome. Its pathogenesis has to be further characterized to develop appropriate targeted therapy.
