Transperitoneal versus extraperitoneal laparoscopic radical prostatectomy during the learning curve: does the surgical approach affect the complication rate?

Purpose: To compare the perioperative complication rate obtained with the transperitoneal laparoscopic radical prostatectomy (TLRP) and with the extraperitoneal LRP (ELRP) during the learning curve (LC). Materials and Methods: Data of the initial 40 TLRP (Group 1) were retrospectively compared with the initial 40 ELRP (Group 2). Each Group of patients was operated by two different surgeons. Results: The overall surgical time (175 min x 267.6 min; p < 0.001) and estimated blood loss (177.5 mL x 292.4 mL; p < 0.001) were statistically better in the Group 1. Two intraoperative complications were observed in Group 1 (5 percent) represented by one case of bleeding and one case of rectal injury, whereas four complications (10 percent) were observed in Group 2, represented by two cases of bleeding, one bladder and one rectal injuries (p = 0.675). Open conversion occurred once in each Group (2.5 percent). Overall postoperative complications were similar (52.5 percent x 35 percent; p = 0.365). Major early postoperative complications occurred in three and in one case in Group 1 and 2, respectively. Group 1 had two peritonitis (fecal and urinary), leading to one death in this group. Conclusions: No statistical differences in overall complication rates were observed. The transperitoneal approach presented more serious complications during the early postoperative time and this fact is attributed to the potential chance of intraperitoneal peritonitis not observed with the extraperitoneal route.

Complete en bloc urinary exenteration for synchronous multicentric transitional cell carcinoma with sarcomatoid features in a hemodialysis patient

The incidence of transitional cell carcinoma (TCC) in patients submitted to hemodialysis is low. The presence of TCC with sarcomatoid features in this cohort is even scarcer. Herein, we describe a very rare case of synchronous multicentric muscle invasive bladder carcinoma with prostate invasion in a hemodialysis patient, submitted to complete en bloc urinary exenteration.

Efficacy of intrarectal lidocaine hydrochloride gel for pain control in patients undergoing transrectal prostate biopsy

OBJECTIVE: To determine the efficacy of intrarectal lidocaine hydrochloride gel in reducing pain in patients undergoing transrectal prostate biopsy. MATERIALS AND METHODS: During the period from June to Noviber 2002, 72 patients undergoing transrectal prostate biopsy at an outpatient service were prospectively randomized. Patients were divided into 2 groups. In group 1, 20 mL of 2 percent lidocaine gel were administered by intrarectal route 15 minutes before biopsy. In group 2 (placebo), 20 mL of ultrasound gel were administered under the same conditions. At the end of the procedure, patients were asked to classify the discomfort degree observed during the procedure through a verbal pain scale. Statistical analysis was performed through qui-square test. RESULTS: The majority of patients in both groups presented slight pain on the examination, and 26 patients (76.4 percent) from group 1, and 26 (68.3 percent) patients from group 2 reported slight pain or no pain at all (p > 0.05). Moderate or intense pain was felt by 23.4 percent of patients in group 1 and 31.5 percent of patients in group 2 (p > 0.05). CONCLUSIONS: We concluded that lidocaine probably exerts a minimal effect on patientsÆ tolerance to pain on transrectal prostate biopsy.

Vesical metastasis of gastric adenocarcinoma

Metastatic vesical tumors are rare, and constitute approximately 1 percent of all neoplasias affecting this organ. The authors report the case of a 63-year old woman with vesical metastasis of gastric adenocarcinoma. Patient presented signs of cachexia and complained of left lumbar pain and dysuria unresponsive to antibiotic therapy for approximately 5 months. She reported a previous partial gastrectomy due to ulcerative undifferentiated gastric adenocarcinoma 1 year and 9 months before. Cystoscopy revealed an extensive vegetative lesion in bladder, occupying its entire mucosal surface. The biopsy revealed metastatic signet-ring cell adenocarcinoma.

Prevalência de coilocitose em biópsias penianas de parceiros de mulheres com lesões genitais induzidas pelo HPV / Prevalence of koilocytosis in penile biopsies of partners of women with HPV-induced genital lesions

OBJETIVO: determinar a prevalência de coilocitose em biópsias penianas de parceiros de mulheres com lesões genitais induzidas pelo HPV e analisar os fatores de risco envolvidos com a infecção peniana. MÉTODOS: foram incluídos neste estudo de coorte transversal 80 parceiros de mulheres com lesões induzidas pelo HPV no período de maio de 2002 a junho de 2003. A média de idade dos pacientes foi de 34,1 anos (variando de 16 a 63). Todos os pacientes negavam ou desconheciam qualquer tipo de lesão genital. Foram submetidos à anamnese específica quanto a presença de sintomas uretrais, passado de doenças sexualmente transmissíveis (DST), número de parceiras sexuais, uso de preservativos e postectomia. Posteriormente foram submetidos à peniscopia com a utilização de soluções de ácido acético e azul de toluidina, tendo sido colhido material para biópsia das lesões de aspecto morfológico sugestivo de contaminação por HPV. A análise estatística foi realizada pelo teste do chi2. RESULTADOS: o exame foi considerado negativo em 24 pacientes (30 por cento). Todos os outros 56 pacientes (70 por cento) apresentaram lesões acetobrancas e azul de toluidina positivas. Destes, 53 foram biopsiados, e 41 pacientes (77,3 por cento) apresentaram biópsia com alterações histológicas sugestivas de infecção pelo HPV. CONCLUSÕES: a prevalência da infecção genital masculina pelo HPV foi de 51,2 por cento, e nenhum fator de risco analisado foi associado com uma maior prevalência da infecção genital pelo vírus.

Spontaneous nephrocutaneous fistula

Spontaneous renal fistula to the skin is rare. The majority of cases develop in patients with antecedents of previous renal surgery, renal trauma, renal tumors, and chronic urinary tract infection with abscess formation. We report the case of a 62-year old woman, who complained of urine leakage through the skin in the lumbar region for 2 years. She underwent a fistulography that revealed drainage of contrast agent to the collecting system and images suggesting renal lithiasis on this side. The patient underwent simple nephrectomy on this side and evolved without intercurrences in the post-operative period. Currently, the occurrence of spontaneous renal and perirenal abscesses is extremely rare, except in patients with diabetes, neoplasias and immunodepression in general.
