RESUMO

PURPOSE: To evaluate the long-term efficacy of laparoscopic Burch colposuspension, we reviewed the success rate and subjective satisfaction rate of this operation for female patients with stress incontinence. Materials and Methods: Between Sep. 1995 and Aug. 1999, 126 patients underwent laparoscopic Burch colposuspension. We reviewed 88 patients who had been followed up for more than 3 years. The mean patient age was 51.1 years and 26 of the 88 patients complained of urge incontinence. All were preoperatively assessed with voiding cystourethrography (VCUG), urodynamic study, cystoscopy and stress, emptying, anatomic, protection, and instability (SEAPI) score. Colposuspension was performed with 2 non- absorbable sutures (n=70) or polyprophylene mesh and Tacker (n=18) by the retroperitoneal approach. RESULTS: At the mean follow-up of 56 months, 58 patients (66%) were cured, and 19 patients (22%) showed significant improvements. Sixty one (94.4%) out of 66 patients who had previously required pad protection attained a pad-free status. Urge incontinence disappeared in 15 out of 26 patients, but 8 (9.1%) patients complained of de novo urge incontinence. The pre- operative factors (age, symptom periods, symptom score, abdominal leak point pressure (ALPP) and VCUG findings) made no difference for the success rate. The subjective satisfaction rate was 93%. The mean operation time was 88 minutes and it decreased to 67 minutes after 50 cases. The mean hospital stay was 3.5 days and mean duration of catheterization was 3.7 days. We had 5 (5.68%) cases of complications: two port site bleeding, one peritoneal injury, one respiratory acidosis and one obturator venous bleeding. However, all of them eventually recovered. CONCLUSIONS: Laparoscopic colposuspension revealed good results on the long-term follow-up, as well the operation as being a minimally invasive procedure. There was a 88% success rate, a 93% subjective satisfaction rate and 94% of the patients became pad free.

RESUMO

PURPOSE: In order to help selecting candidates for nephron-sparing surgery, the pre-operative clinical parameters that can predict a renal insufficiency developing after a radical nephrectomy even in patients with contralateral normal kidney were identified. MATERIALS AND METHODS: Of 551 patients who underwent a radical nephrectomy to treat a renal cell carcinoma, 213 patients with a pre-operative serum creatinine >2.0mg/dl or with synchronous bilateral or metastatic tumors were excluded. In 338 patients (male 227, female 111), the incidence of post-operative renal insufficiency was evaluated. Using Kaplan-Meier's method, the clinical parameters including age, sex, pre-operative serum creatinine level, hypertension and diabetes mellitus were evaluated to determine if they could be used to predict a post-nephrectomy creatinine failure, which was defined as a serum creatinine >2.0mg/dl. RESULTS: Of the 338 patients, creatinine failure had developed in 25 (6.1%) at post-operative 8 months (1-72 months). The mean pre-operative serum creatinine level of these patients was 1.35mg/dl. Six patients were older than 60, 16 patients had hypertensive and 8 patients were diabetic. In 2 patients, hemodialysis was required due to a progressive post-operative deterioration in the renal function. Multivariate analysis revealed that all the pre-operative clinical parameters such as old age (>60 years), male sexuality, hypertension, diabetes mellitus and an elevated serum creatinine level (>1.4mg/dl) were significant independent predictors of a post-nephrectomy renal insufficiency (p< 0.05). CONCLUSIONS: Patients with clinical factors including old age, male sexuality, hypertension, diabetes mellitus and an elevated creatinine value have an increased risk of a renal insufficiency after a radical nephrectomy even though the contralateral kidney is normal. Therefore, in these patients nephron-sparing surgery is strongly recommended.

RESUMO

PURPOSE: This study evaluated the accuracy of helical CT angiography (HCTA) in a preoperative evaluation of living renal transplant donors (LRTDs) for visualizing the renal vascular anatomy with an emphasis on identifying the number of renal arteries and the presence of small branches and venous anomalies. MATERIALS AND METHODS: From Jan. 2000 to Feb. 2001, a total of 50 potential LRTDs were evaluated with conventional renal angiography (CRA) and HCTA. All candidates then underwent a donor nephrectomy. The HCTA was done according to a standard HCTA protocol. The intraoperative findings on the number of renal vessels were compared with those of the CRA and HCTA respectively. RESULTS: There was an overall agreement on the number of renal arteries and veins between the CRA findings and 3-D reconstruction of the HCTA (91%, 95%). The overall accuracies for predicting the number of renal arteries and veins relative to the intraoperetive findings were 84%, 94% for CRA and 80%, 94% for HCTA respectively. The CRA missed 8 accessory renal arteries while HCTA missed 10. In HCTA, cases with an accessory renal artery with a diameter < or =5 Fr. (1.65mm) and two cases of an early branching single vessel simulating dual arteries, were misdiagnosed. Despite the misdiagnosed cases, there was no significant intraoperative morbidity. The HCTA revealed another lesion of a renal parenchyme, the urinary collecting system and other viscera. There were no significant complications in the process of both techniques. The cost of HCTA was 48% less than the CRA plus the excretory urography (EU) for imaging the potential LRTDs. CONCLUSIONS: A HCTA appears to be as accurate as a CRA for visualizing the renal vascular anatomy in the preoperative assessment of potential LRTDs. A HCTA has the potential to be a good alternative to a CRA plus EU for assessing potential LRTDs.

RESUMO

Purpose: Computed tomography (CT) is commonly used for the clinical staging of bladder cancer. However, a previous transurethral resection (TUR) often results in an overestimation of a proper muscle and perivesical fat invasion in the CT. The purpose of this study was to evaluate the effects of a TUR on CT staging in patients with bladder cancer. MATERIALS AND METHODS: A total of 67 patients who underwent a radical cystectomy for primary bladder cancer were included in this study. CT was performed before a TUR in 38 patients (group 1) and after a TUR in 29 (group 2). In each patient, CT evaluated the presence or absence of a proper muscle and perivesical fat invasion and the findings were then compared with the histopathologic findings following the radical cystectomy. RESULTS: CT had an overall staging accuracy of 79.1% for a proper muscle invasion and 67.2% for a perivesical fat invasion. For a proper muscle invasion, there was a significant difference between both groups in the CT specificity (76.9% vs. 30.0%, p=0.024) while no difference in the sensitivity (92.0% vs. 89.5%) was noted. For a perivesical fat invasion, there was also a significant difference between the two groups in terms of the CT specificity (75.0% vs. 35.7%, p=0.022) while there was no difference in the sensitivity (72.2% vs. 80.0%). CONCLUSIONS: A TUR before a CT may cause a false positive result in the clinical staging of bladder cancer using CT. Therefore, to minimize the confounding effect of a TUR on CT staging, it is strongly recommended that a CT be performed before a TUR in the case of a highly suspicious invasive bladder cancer.
