Urinary Tract Endometriosis: A Multidisciplinary Fight Against a Silent Enemy.

STUDY OBJECTIVE: To demonstrate the safety and feasibility of laparoscopic robotic assisted approach to urinary tract endometriosis. DESIGN: This is an educational video to explain the main steps of robotic assisted ureteroneocystostomy owing to endometriosis. SETTING: Tertiary care university hospital. A patient written consent was obtained on March 9, 2021. The local institutional review board confirmed that the video met the ethical criteria. INTERVENTIONS: Laparoscopic robotic assisted resection of uterosacral ligament endometriotic nodule, left terminal partial ureterectomy, partial cystectomy, and ureteroneocystostomy. CONCLUSION: This video shows a stepwise approach to laparoscopic robotic assisted urinary tract endometriosis management demonstrating its feasibility and safety. Urinary tract endometriosis affect only the 0.3% to 6% of women affected by endometriosis, among which the most common localization is the bladder (84%-90%) [1]. The ureteral compression is rare but can lead to obstruction up to silent loss of renal function [2], which is one of the main factors to take into account in the management of this disease [3].

Perineal schwannoma: an unusual tumor and clinical presentation - first case with erectile dysfunction associated with this neoplasm.

INTRODUCTION: Perineal schwannomas (PS) are very rare benign tumors with few cases reported in literature and none of these reports erectile dysfunction among clinical presentations. CASE DESCRIPTION: We report a case of PS with unusual clinical presentation showing erectile dysfunction associated with perineal pain and discomfort during defecation, and the postoperative residual pain and erectile dysfunction treatment. CONCLUSIONS: On the basis of a literature review of all cases reported and on our case reported, we have delineated a clinical, diagnostic, and therapeutic profile of PS, summarized in a useful table.

Pelvic urothelial carcinoma with nested pattern of growth and an uncommon clinical presentation: a case report.

BACKGROUND: Nested variant of urothelial carcinoma (NVUC) is a rare and often unrecognized urothelial neoplasia. Diagnosis is based on morphology only, and no immunohistochemical or cytogenetic differences from usual high-grade urothelial carcinomas have been reported. CASE: We describe the case of a 49-year-old woman affected by hepatitis C virus presented with fever, discomfort, urgency, and hypertension. Computed tomography showed a sclerosing inflammatory process involving the connective and adipose tissue of the renal sinus. In the absence of renal or pelvic masses an underlying malignancy was excluded and renal abscess or tuberculosis was suspected. Accordingly, nephrectomy and proximal ureterectomy was performed. Grossly, calices, renal pelvis, and pyeloureteral junction appeared modestly dilated with whitish, thickened, and uneven mucosa. Microscopically, the subepithelial connective tissue, the fibromuscular layer, and the renal sinus fat were diffusely infiltrated by small nests of medium to large urothelial cells (p63 positive) with abundant eosinophylic cytoplasm and slightly atypical nuclei. CONCLUSION: On the basis of morphologic and immunohistochemical features, a diagnosis of NVUC was made. After surgery, the patient recovered from hypertension. Pelvic and upper urothelial tract NVUCs are uncommon, and to the best of our knowledge, this is the second case of NVUC with renal involvement.
