[Rigid ureteroscopy in the case of suspected tumor of the upper urinary tract: report of 63 cases].
OBJECTIVE: This retrospective study was designed to determine the place of rigid ureteroscopy in the diagnosis of upper urinary tract tumours. MATERIAL AND METHODS: 63 patients (45 males and 18 females) with a mean age of 60 years, were investigated by rigid ureteroscopy for suspected upper urinary tract tumour. The Wolf 8-9.8 F ureteroscope was used in the case of suspected upper urinary tract tumour in a context of ureteric obstruction on the IVU in 29 cases, haematuria in 23 cases, a defect on retrograde ureteropyelography in 5 cases, suspicious CT scan in 5 cases and positive cytology with normal cystoscopy in 2 cases. RESULTS: The ureteroscope was able to be advanced as far as the suspicious zone in 89% of cases. The mean operating time was 48 minutes and the mean hospital stay was 3.2 days. Diagnostic rigid ureteroscopy has a Sensitivity of 58% (95% confidence interval CI95: +/- 28), a Specificity of 100%, a Positive Predictive Value of 100%, a Negative Predictive Value of 91% (+/- 7) and a low morbidity (3%). CONCLUSION: Rigid ureteroscopy does not appear to be the examination of choice for the diagnosis of upper urinary tract tumours, as it cannot investigate the renal pelvis or calices and the ureteroscope cannot always be advanced to the suspicious zone. The flexible ureteroscope now appears to be a more reliable diagnostic tool.

Comparison of a phytotherapeutic agent (Permixon) with an alpha-blocker (Tamsulosin) in the treatment of benign prostatic hyperplasia: a 1-year randomized international study.
OBJECTIVE: While the lipido-sterolic extract of Serenoa repens (LSESr)-Permixon((R))-has been shown to have an equivalent efficacy to finasteride in patients with benign prostatic hyperplasia (BPH), to date, there has been no valid comparison of phytotherapy with alpha-blockers. The aim of this study was to assess the equivalent efficacy of Permixon and tamsulosin. METHODS: Eight hundred and eleven men with symptomatic BPH (I-PSS> or =10) were recruited in 11 European countries for a 12-month, double-blind randomized trial. After a 4-week run-in period, 704 patients were randomly assigned to either tamsulosin 0.4mg/day (N=354) or Permixon 320mg/day (N=350). I-PSS, QoL and Q(max) were evaluated at baseline and periodically for 1 year. Prostate volume and serum prostate-specific antigen (PSA) were measured at selection and at endpoint. The endpoint analysis was performed on the per-protocol population of 542 patients (tamsulosin: N=273; Permixon: N=269). RESULTS: At 12 months, I-PSS decreased by 4.4in each group and no differences were observed in either irritative or obstructive symptom improvements. The increase in Q(max) was similar in both treatment groups (1.8ml/s Permixon, 1.9ml/s tamsulosin). PSA remained stable while prostate volume decreased slightly in the Permixon-treated patients. The two compounds were well tolerated, however, ejaculation disorders occurred more frequently in the tamsulosin group. CONCLUSION: This study demonstrates that Permixon and tamsulosin are equivalent in the medical treatment of lower urinary tract symptoms in men with BPH, during and up to 12 months of therapy.

OBJECTIVE: While the lipidosterolic extract (LSESr) of Serenoa repens--Permixon--has been shown to have an equivalent efficacy to finasteride in patients with benign prostatic hyperplasia (BPH), to date, there has been no valid comparison of phytotherapy with alpha-blockers. The aim of this study was to assess the equivalent efficacy of Permixon and tamsulosin. METHODS: Eight hundred and eleven men with symptomatic BPH (international prostdate symptom score, I-PSS > or = 10) were recruited in 11 European countries for a 12-month, double-blind randomized trial. After a 4-week run-in period, 704 patients were randomly assigned to either tamsulosin 0.4 mg per day (N = 354) or Permixon 320 mg per day (N = 350). I-PSS, QoL and maximum urinary flow rate (Qmax) were evaluated at baseline and periodically for 1 year. Prostate volume and serum prostate-specific antigen (PSA) were measured at selection and at endpoint. The endpoint analysis was performed on the per-protocol (PP) population of 542 patients (tamsulosin: N = 273; Permixon: N = 269). RESULTS: At 12 months, I-PSS decreased by 4.4 in each group and no differences were observed in either irritative or obstructive symptom improvements. The increase in Qmax was similar in both treatment groups (1.8 ml/s Permixon, 1.9 ml/s tamsulosin). PSA remained stable while prostate volume decreased slightly in the Permixon-treated patients. The two compounds were well tolerated, however, ejaculation disorders occurred more frequently in the tamsulosin group. CONCLUSION: This study demonstrated that Permiwon and tamsulosin are equivalent in the medical treatment of lower urinary tract symptoms in men with BPH, during and up to 12 months of therapy.
