ABSTRACT
ABSTRACT Introduction There is a lack of studies in our national scenario regarding the results obtained by laparoscopic radical prostatectomy technique (LRP). Except for a few series, there are no consistent data on oncological, functional, and perioperative results on LRP held in Brazil. As for the LRP technique performed by extraperitoneal access (ELRP), when performed by a single surgeon, the results are even scarcer. Objective To analyze the early perioperative and oncologic results obtained with the ELRP, throughout the technical evolution of a single surgeon. Patients and methods A non-randomized retrospective study was held in a Brazilian hospital of reference. In the 5-year period, 115 patients underwent the ELRP procedure. Patients were divided into two groups, the first 57 cases (Group 1) and the following 58 cases, (Group 2). A comparative analysis between the groups of efficacy results and ELRP safety was carried out. Results The average age of patients was 62.8 year-old and the PSA of 6.9ng/dl. The total surgery time was 135.8 minutes on average, and the urethral-bladder anastomosis was 21.9 min (23.3 min versus 20.7 min). The positive surgical margins (PSM) rate was 17.1%, showing no difference between groups (16.4% versus 17.9%; p=0.835). There was statistical difference between the groups in relation to the anastomosis time, estimated blood loss and the withdrawal time of the urinary catheter. Conclusion The ELRP technique proved to be a safe and effective procedure in the treatment of prostate cancer, with low morbidity.

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.

Recent advances in techniques of imaging and ablation have led to the application of several minimally invasive modalities, such as radiofrequency ablation (RFA) with a success rate varying from 79 to 96 percent and a serious complication rate of 1 to 4 percent in the treatment of small renal tumors. The authors report on the case of a 67-year-old patient with a radiofrequency ablation complication, stenosis of the ureteropelvic junction in one kidney, and analyze the results of this modality for the treatment of renal tumors.

OBJECTIVES: The treatment of recurrent prostate cancer after radiotherapy or brachytherapy through radical prostatectomy has been little indicated due to the concern over the procedure's morbidity. We present the experience of our service with postradiotherapy radical prostatectomy. MATERIALS AND METHODS: Between 1996 and 2002, 9 patients submitted to radiotherapy due to prostate cancer were treated with salvage surgery for locally recurrent disease. All patients had a biopsy of the prostate confirming the tumor recurrence, increase in the PSA levels and staging without evidence of a systemic disease. We have assessed the morbidity and the recurrence-free survival rate after salvage radical prostatectomy. RESULTS: Preradiotherapy PSA varied from 6.2 to 50 ng/mL (mean 17.3) and clinical staging T1, T2 and T3 in 33.3 percent, 44.4 percent and 22.2 percent of the patients respectively. The interval for the biopsy after conforming external beam radiotherapy or brachytherapy varied from 8 to 108 months (median: 36). Four patients received antiandrogenic therapy neoadjuvant to the surgery with a mean of 7 months (1-48) after radiotherapy. From the six patients potent before the surgery, three have presented erectile dysfunction. Urinary incontinence as well as bladder neck sclerosis occurred in two patients (22.2 percent). Biochemical recurrence occurred in two individuals (22.2 percent) 12 months after the surgery. Biochemical recurrence-free survival rate was 77.8 percent with median follow-up time of 30 months (8-102). CONCLUSION: Salvage radical prostatectomy is a safe and effective alternative for the treatment of locally recurrent prostate cancer after radiotherapy and brachytherapy.

Primary renal lymphoma is a rare lesion that represents less than 1 percent of the kidneys lesions. The authors discuss the case of a 67-year-old woman with a renal mass identified 7 years after treatment of a non-HodgkinÆs lymphoma, and analyze clinical and prognostic aspects of renal lymphomas. Radiological findings in this case showed an uncommon presentation of the renal lymphomatous lesion which served as a warning that tumors might appear during follow-up as atypical and uncommon lesions.

Vesicourethral anastomotic stricture and urinary incontinence are severe complications of radical prostatectomy because they cause great impact in the quality of life. Three patients that presented these complications after prostate radical surgery were assessed retrospectively. To treat the stenosis of the vesicourethral anastomosis an urolume was placed and later on, an artificial sphincter AMS 800 was implanted to treat the resulting urinary incontinence.
