RESUMO
AIMS: To evaluate the collagen content in the bladder wall of men undergoing open prostate surgery. METHODS: From July 2014 to August 2016, men aged ≥ 50 years, presenting LUTS and undergoing open prostate surgery due to benign prostatic enlargement (BPE) or prostate cancer were prospectively enrolled. Preoperative assessment included validated questionnaires (IPSS and OAB-V8), lower urinary tract ultrasound, and urodynamics. Bladder biopsies were obtained during open prostatectomy for determination of collagen content (sirius red-picric acid stain; polarized light analysis). Collagen to smooth muscle ratio (C/M) in the detrusor was measured and its relationship with preoperative parameters was investigated. The level of significance was P < 0.05. RESULTS: Thirty-eight consecutive patients were included in this pilot study. Mean age was 66.36 ± 6.44 years and mean IPSS was 11.05 ± 8.72 points. Men diagnosed with diabetes mellitus (DM2) were found to have higher collagen content in the bladder wall when compared to non-diabetic patients (17.71 ± 6.82% vs 12.46 ± 5.2%, respectively; P = 0.024). Reduced bladder compliance was also marker for higher collagen content (P = 0.042). Bladder outlet obstruction (BOO) was not a predictor of increased collagen deposition in the bladder wall (P = 0.75). Patients with PVR ≥ 200 mL showed a higher collagen to smooth muscle ratio in the bladder wall (P = 0.036). CONCLUSIONS: DM2 and urodynamic parameters, such as increased PVR and reduced bladder compliance, were associated with higher collagen content in the bladder wall of men with LUTS.

Introducción: El cáncer de vesícula ocupa el 5° lugar de aparición de todos cánceres digestivos. En nuestro país es dos veces más frecuente que los tumores ubicados en la vía biliar principal intra o extrahepática. Objetivos: Reporte de caso y revisión bibliográfica. Reporte de Caso: Mujer de 52 años, sin antecedentes clínicos de relevancia, que consulta por dolor abdominal, náuseas y vómitos de 14 días de evolución. Se realiza una ecografía que evidencia engrosamiento parietal y litiasis vesicular. En el intraoperatorio se evidencia Vesícula en Porcelana con infiltración hepática a nivel del fondo.Discusión: Destacar la importancia de una correcta interpretación de las imágenes, a los fines de tomar la conducta que mayor beneficio representa para el paciente.

Introduction: Gallbladder cancer occupies the 5th place of occurrence among all digestive system cancers. In our country, it is twice more frequent than tumors of the intra or extrahepatic principal biliary tract. Objectives: Case report and literature review. Case Report: 52-year-old woman, with no relevant clinical history, with 14 days of abdominal pain, nausea and vomit. The ultrasound scan reveals parietal thickening and gallstones. During intrasurgical exploration, porcelain gallbladder is found, with hepatic infiltration at fundus. Discussion: To highlight the importance of a correct image interpretation, in order to choose the most beneficial treatment for the patient. (AU)
