Umbilical KeyPort bilateral laparoscopic orchiectomy in patient with complete androgen insensitivity syndrome

MAIN FINDINGS: A 22-year-old woman with complete androgen insensitivity syndrome (CAIS) presenting with primary amenorrhea and normal female external genitalia was referred for laparoscopic gonadectomy. She had been diagnosed several years earlier but was reluctant to undergo surgery. CASE HYPOTHESIS: Diagnosis of this X-linked recessive inherited syndrome characterizes by disturbance of virilization in males with an AR mutation, XY karyotipe, female genitalia and severely undescended testis with risk of malignization. The optimal time to orchidectomy is not settled; neither the real risk of malignancy in these patients. Early surgery impacts development of a complete female phenotype, with enlargement of the breasts. Based on modern diagnostic imaging using DCE-MRI and surgical technology with single port laparoscopic access we hypothesize that the optimum time for gonadectomy is not at the time of diagnosis, but once feminization has completed. PROMISING FUTURE IMPLICATIONS: An umbilical laparoendoscopic single-site access for bilateral gonadectomy appears to be the first choice approach as leaves no visible incision and diminishes the psychological impact of surgery in a patient with CAIS absolutely reassured as female. KeyPort, a single port access with duo-rotate instruments developed by Richard Wolf facilitates this surgery and allows excellent cosmetic results.

Clamp ablation of the testes compared to bilateral orchiectomy as androgen deprivation therapy for advanced prostate cancer

PURPOSE: Burdizzo clamp ablation of the testes (CAT) may provide an incisionless, cost-effective form of androgen deprivation therapy (ADT) in men with adenocarcinoma of the prostate (ACP) who find bilateral orchiectomy (BO) unacceptable or can not afford medical ADT. The aim of this study was to compare CAT with BO as primary ADT in men with ACP. MATERIALS AND METHODS: Written, informed consent was obtained from men with locally advanced or metastatic ACP. Patients were prospectively randomized to BO (n = 9) or CAT (n = 10) under local anaesthesia, and were evaluated 3 and 7 days, 6 weeks and 3 months post-procedure. The protocol was approved by the local institutional ethics committee. Statistical analysis was performed using Student's, Mann-Whitney's and Fisher's tests. RESULTS: Mean duration of the procedure was significantly longer for BO than CAT (16.9 vs. 10.9 minutes). Mean pain scores during and after the procedure did not differ significantly. Serum testosterone decreased significantly on days 3 and 7 after CAT, but increased at 6 weeks, and was significantly higher than after BO. Serum luteinizing hormone increased significantly from day 3 after BO and from day 7 after CAT. Serum prostate specific antigen decreased significantly after BO, but not after CAT. Minor complications were more common after BO (89 percent) than CAT (40 percent). In the 9 men who did not achieve castrate levels of testosterone after CAT, BO was performed. CONCLUSIONS: CAT was quicker to perform and had a lower complication rate, but was not as effective as BO in achieving castrate serum testosterone levels.

Uso de malla de polipropileno subalbugínea en orquiectomía bilateral por cáncer de próstata / Use of a testicular intralbugineal polypropylene mesh in bilateral orchiectomy for prostate cancer

Se presenta la experiencia del Servicio de Urología del Hospital Carlos Van Büren en el uso de malla de polipropileno intralbugínea como prótesis testicular, contemporánea a la orquiectomía subalbugínea bilateral por cáncer de próstata. Nuestra serie es de 30 pacientes, con un total de 60 testículos, correspondientes al período comprendido entre noviembre de 2001 y septiembre de 2002. Los resultados iniciales son alentadores.
