Clear cell myomelanocytic tumour: minimally invasive treatment of a rare bladder tumour.

Clear cell myomelanocytic tumours are extremely rare neoplastic growths considered to be members of the family of perivascular epithelioid cell tumours (PEComas), which have in common the coexpression of melanocytic and smooth muscle immunohistochemical markers. These tumours are known to be ubiquitous with uncertain tumour biology and to have unpredictable clinical behaviour. They have been reported in the genitourinary tract, including the kidney and prostate.

Externalized urachal suture: novel approach to bowel and bladder retraction during transperitoneal laparoscopic radical prostatectomy.

Introduction: Although laparoscopic radical prostatectomy (LRP) has emerged as a legitimate minimally invasive surgical alternative to open radical retropubic prostatectomy, the technical difficulty of this advanced laparoscopic procedure remains an obstacle to its widespread use. We report a novel surgical technique for the purpose of bowel and bladder retraction during transperitoneal LRP that improves visualization and negates the need for additional working ports or steep Trendelenburg positioning.

Technical Considerations: A 35-cm absorbable suture is secured intracorporeally to the urachus.
