Brito, Artur H.;Mitre, Anuar I.;Srougi, Miguel;
International braz j urol , 2006, DOI: 10.1590/S1677-55382006000300006
Abstract: introduction: this work evaluates the results of ureteroscopic treatment of impacted ureteral stones with a pneumatic lithotripter. materials and methods: from march 1997 to may 2002, 42 patients with impacted ureteral stones were treated by retrograde ureteroscopic pneumatic lithotripsy. twenty-eight patients were female and 14 were male. the stone size ranged from 5 to 20 mm. the ureteral sites of the stones were distal in 21, middle in 12 and proximal in 9. results: considering stones with distal location in the ureter, 1 patient had ureteral perforation and developed a stricture in the follow-up (4.7%). as for stones in the middle ureter, 2 perforations and 1 stricture were observed (8.3%) and regarding stones located in the proximal ureter, 5 perforations and 4 strictures occurred (44%). in the mid ureter, 1 ureteral avulsion was verified. in 34 patients without ureteral perforation, only 1 developed a stricture (2.9%). of 8 patients who had perforation, 6 developed strictures. the overall incidence of stricture following treatment of impacted ureteral calculi was 14.2%. conclusions: ureteroscopy for impacted ureteral calculi is associated with a higher incidence of ureteral perforation and stricture. ureteroscopy of proximal ureteral calculi is associated with a high risk of perforation, when compared to mid or distal ureteral calculi. ureteral perforation at the site of the stone seems to be the primary risk factor for stricture formation in these cases.

International braz j urol , 2005, DOI: 10.1590/S1677-55382005000400009
Abstract: we discuss the case of a 13-year old boy with urinary infection who was preoperatively diagnosed with left vesicoureteral reflux associated with paraurethral saccule. laparoscopic lich-gregoir anti-reflux surgery was then proposed. intraoperatively, we observed segmental megaureter that was successfully treated by the proposed technique without ureteral modeling, contrary to the rule that respects the 3-5 times ratio between the submucous path and the ureteral diameter.

Pinto, Antonio C.;Baracat, Fabio;Montellato, Nelson D.;Mitre, Anuar I.;Lucon, Antonio M.;Srougi, Miguel;
International braz j urol , 2007, DOI: 10.1590/S1677-55382007000600011
Abstract: objectives: to evaluate the impact of surgical treatment of stress urinary incontinence on the sexual function of women and to identify whether such treatment can improve their sexual function and overall quality of life. materials and methods: 64 heterosexual women with such indication were studied using the female sexual function index (fsfi) questionnaire, modified by introducing one question to evaluate the impact of urine loss. this was applied preoperatively and six months after surgery. result: among these 64 patients, 60.94% had regular sexual activity, while 39.06% did not. among sexually active patients, 59% had urine loss during sexual intercourse and, of these, 87% had urine losses in half or more of sexual relations. there were no statistically significant differences in assessments of desire, arousal, lubrication, orgasm, satisfaction and pain, or in totaling the scores, between the preoperative period and six months after surgical treatment. however, the scores for urine losses during sexual intercourse were significantly better after the operation. conclusions: analysis of the results allowed the following conclusions to be reached: urine lost during sexual activity was frequent among patients with stress urinary incontinence. suburethral support surgery did not jeopardize sexual activity. patients cured of stress urinary incontinence did not present improvement in sexual function.

Abstract: OBJECTIVE: To present the initial experience of videolaparoscopic nephrectomy in live renal donor. MATERIALS AND METHODS: In the period from April 2000 to August 2003, 50 left nephrectomies in live donor were performed by videolaparoscopy for transplantation. Twenty-eight patients were male (56%) and 22 female (44%). Mean age was 37.2 years, and the mean body mass index (BMI) was 27.1 kg/m2. RESULTS: Mean surgical time was 179.5 minutes, and warm ischemia time of the graft was 3.79 minutes. The mean estimated bleeding was 141 mL. There was no need of blood transfusion or conversion to open surgery. In 42 cases (84%), the vascular portion of the graft was considered good by the recipient's surgical team and in all cases, the ureter was considered of proper size, though in one of them (2%) its vascularization was considered improper. The transplanted kidneys produced urine still in the surgical room in 46 of the 50 transplantations considered. In only 2 cases opioid was required for analgesia. In average, 3.1 doses of dipyrone were used for each patient during hospital stay, and hospital discharge occurred, in average, after 3.2 days post-operatively. Two patients required re-operations and one of them evolved to death. CONCLUSIONS: The laparoscopic nephrectomy in live donor for renal transplantation is an alternative to conventional open surgery. In relation to the graft, no alteration, either anatomic or functional, was detected. Though there is already a large documentation in the international literature regarding this procedure, in our setting a prospective randomized study with the usual surgical study is still necessary in order to prove the advantages and disadvantages of the method.

Abstract: OBJECTIVE: Compare two different techniques for laparoscopic live donor nephrectomy (LDN), related to the operative costs and learning curve. MATERIALS AND METHODS: Between April/2000 and October/2003, 61 patients were submitted to LDN in 2 different reference centers in kidney transplantation. At center A (CA), 11 patients were operated by a pure transperitoneal approach, using Hem-O-Lokò clips for the renal pedicle control and the specimens were retrieved manually, without using endobags. At center B (CB), 50 patients were also operated by a pure transperitoneal approach, but the renal pedicles were controlled with endo-GIA appliers and the specimens were retrieved using endobags. RESULTS: Operative time (231 ? 39 min vs. 179 ? 30 min; p < 0.000), warm ischemia time (5.85 ? 2.85 min vs. 3.84 ? 3.84 min; p = 0.002) and blood loss (214 ? 98 mL vs. 141 ? 82 mL; p = 0.02) were statistically better in CB, when compared to CA. Discharge time was similar in both centers. One major complication was observed in both centers, leading to an open conversion in CA (9.1%). One donor death occurred in CB (2%). Regarding the recipients, no statistical difference was observed in all parameters analyzed. There was an economy of US$1.440 in each procedure performed in CA, when compared to CB. CONCLUSIONS: Despite the learning curve, the technique adopted by CA, showed no deleterious results to the donors and recipients when compared with the CB. On the other hand, this technique was cheaper than the technique performed in the CB, representing an attractive alternative for LDN, mainly in developing centers.

Abstract: Objetivo: cálculos urinários atingem de 5 a 10% da popula o em alguma fase da vida. Destes casos, somente 2 a 3% s o crian as. O tratamento da litíase urinária na faixa pediátrica, com o uso de métodos minimamente invasivos, representa uma alternativa cada vez mais atraente. O presente trabalho objetiva apresentar resultados de litotripsia extracorpórea como tratamento minimamente invasivo de litíase urinária na infancia. Métodos: no período de setembro de 1991 a setembro de 2000, foram tratadas e acompanhadas 87 crian as, sendo que seis delas tinham dois cálculos; portanto foram tratados 93 cálculos urinários. Foi utilizado o equipamento de litotripsia extracorpórea por ondas de choque, da Dornier-Philips. Resultados: os cálculos piélicos, caliciais superiores e médios foram fragmentados e eliminados na porcentagem de 87,7% e 77,8%, respectivamente. Os cálculos localizados no cálice inferior foram eliminados em 64,7%. Dos três casos de cálculo coraliforme, somente um ficou livre do cálculo (33,3%). Os dez pacientes com cálculo ureteral ficaram livres de litíase (100%). Os cálculos vesicais foram tratados e eliminados em 60% dos casos. Conclus o: a litotripsia extracorpórea demonstrou ser uma forma eficiente de tratamento de cálculos piélicos, caliciais, ureterais e vesicais em crian as. Cálculos coraliformes n o tiveram bons resultados quando tratados por meio de litotripsia extracorpórea. Os resultados deste método foram influenciados pela localiza o e tamanho dos cálculos.

Abstract: 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%) represented by one case of bleeding and one case of rectal injury, whereas four complications (10%) 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%). overall postoperative complications were similar (52.5% x 35%; 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.
