RESUMEN
BACKGROUND: Monosymptomatic enuresis (MNE) results from a pathogenic triad that may include lack of vasopressin secretion during sleep, reduced functional bladder capacity and inability to wake up during sleep. The treatment of MNE can be performed through behavioral therapy, use of alarms or medications such as desmopressin and imipramine. OBJECTIVE: To compare the effectiveness of different treatments of MNE. STUDY DESIGN: Prospective and randomized study comparing different intervention and a control group (receiving only behavior therapy) for MNE. INCLUSION CRITERIA: age between 5 and 16 years old, with MNE, evaluated at the pediatric urology outpatient clinic of Hospital Infantil Menino Jesus. At first visit children were submitted to behavior therapy (urotherapy) for 3 months, children were subsequently characterized according to the ICCS as non-responders, partial responders, or full responders. Those partial responders or non-responders received a patient ID and were randomized to four groups: Alarm Group (G1), Desmopressin Group - DDAVP (G2), Imipramine Group (G3) and Control (G4). All groups were monitored monthly, for a period of 6 months. After 6 months, the children were reevaluated for MNE. RESULTS: 93 patients were enrolled. Mean age was 10.96 years with a standard deviation of 2.28 years, 59,1% were male. All groups had improvement in the number of dry nights (Table). Taking in account success the population full responders and partial responders: Alarm Group (G1) achieve success in 100% of cases, Desmopressin Group - DDAVP (G2) in 63.6% of cases, Imipramine Group (G3) in 73.7% of cases (Table 3). No drugs side effects were observed in both groups (G2 and G3), there was no dropout in patients who used alarms. DISCUSSION: Our data suggests that the use of alarms is the most effective treatment of ENM with superior results when compared to imipramine and DDAVP. The small number of participants is a weakness of the study, as well as the lack of a voiding diary at the end of the study. CONCLUSION: All therapeutics options utilized in the treatment of MNE are safe, effective and has a low rate of abandonment.

AIMS: Evaluate the efficacy of biofeedback and parassacral electric nerve stimulation (TENS) for the treatment of children with lower urinary tract (LUT) dysfunction. METHODS: A prospective, randomized study was approved by our Hospital Ethics Committee. We enrolled 64 children, 43 girls and 21 boys, average age of 9.39 years. The initial evaluation consisted of history, physical examination, urine analyses, voiding diary, uroflow, and ultrasound. Dysfunction voiding symptom score (DVSS) questionnaires were applied pre- and post-treatment. The children were divided into two treatment groups independent of the predominant type of voiding dysfunction (dysfunctional or overactive bladder): biofeedback group and TENS group. The criteria for assessing the effectiveness of the techniques was the resolution of daytime and nighttime symptoms including urinary leakage, improvements in voiding diary, DVSS, and changes in uroflow. After 6 months, the children were reassessed with the same work-up of baseline. RESULTS: Regarding daytime symptoms, results for complete response were similar between the two groups (P = 0.483); 54.9% of children treated by the biofeedback group and 60.6% in the TENS group. The same have been observed in the nighttime incontinence with complete resolutions in 29.6% and 25%, respectively ( P = 0.461). Analyzing the voiding diary, uroflow and DVSS questionnaires both groups had significant improvement ( P = 0.001) after treatment. The biofeedback group required fewer sessions than TENS group, 10.9 and 18.1, respectively ( P < 0,001). CONCLUSIONS: Both biofeedback and the TENS are equally effective for treating non-neurogenic voiding dysfunction. Biofeedback seems to require a lower number of sessions to obtain similar results of the TENS.

PURPOSE: A growing body of evidence suggests that low testosterone can be an independent predictor of adverse clinicopathological features and worse prognosis in prostate cancer (PCa) patients. However, this association is still incompletely understood and the results are divisive. The aim of this study was to analyze testosterone as a predictor of aggressive disease in subjects with clinically localized PCa. MATERIALS AND METHODS: A cohort was conducted including the patients submitted to radical prostatectomy in our institution during a period of four years. The patients had clinically localized disease and their total testosterone (TT) was routinely measured preoperatively in the morning before surgery. They were stratified in groups with low (< 300 ng/dL) and normal TT (≥ 300 ng/dL). Tumor aggressiveness was inferred based on preoperative PSA levels, pathological Gleason score (lower, equal or greater than 7), TNM stage and surgical margins status. RESULTS: After analyzing 164 patients we found a significant association between mean preoperative TT and extraprostatic disease (379 for pT3 vs. 421 ng/for pT2 - p < 0.001, AUC > 0.99). Conversely, men with high Gleason score had similar mean TT compared to those with lower scores. Preoperative low TT (defined as TT < 300 ng/dL) could not be statistically correlated with either preoperative PSA levels, pathological Gleason score, extraprostatic extension, positive surgical margins or seminal vesicles involvement. CONCLUSIONS: This study indicates that testosterone may be a useful predictive tool once pathological extraprostatic extension was somewhat signaled by lower TT levels preoperatively. However, it does not consolidate a clear association between aggressive tumor biology and hypogonadism.

PURPOSE: To analyze the influence of urethral mobility and Valsalva leak point pressure on postoperative outcomes of transobturator sling (TOT) for female stress urinary incontinence. MATERIALS AND METHODS: A prospective cohort was conducted including 66 patients submitted to TOT from March 2006 to May 2009. Urethral hypermobility was defined as mobility ≥ 30° on Q-tip test, and Valsalva leak point pressure (VLPP) was classified as greater than 60 cmH2O or 60 and less on preoperative urodynamics. These parameters were compared through well defined postoperative objective and subjective success criteria. Intensity of urinary leakage and quality of life was analysed by ICIQ-SF. Statistical analysis was accomplished and the results rendered significant if p < 0.05. RESULTS: Mean follow up was 10 months (3 to 28). Mean age was 55 years (33 to 80), 70% were white and 30% African descendent, mean body mass index was 27 (21 to 38), average vaginal and abdominal deliveries were 2.8 and 0.5 respectively. A quarter had prior stress incontinence surgery. Patients with urethral hypermobility had higher objective success rates (98% versus 81.25%, p = 0.04). The subjective success rate was also greater in the hypermobility group (84% versus 62.5%), but statistical significance was not reached (p = 0.07). VLPP had no influence on either objective or subjective postoperative success rates (p = 0.17 and 0.34, respectively). In the subgroup analysis, those with low mobility and high VLPP had worse objective success rates in comparison to the group with hypermobility and low VLPP (p = 0.04) and also in relation to the remaining of the studied population. Other possible prognostic factors (previous surgery, mixed incontinence, gestational status) had no influence on success rates. CONCLUSIONS: High urethral mobility, regardless of the sphincteric status indicated by VLPP, is a favorable prognostic factor for tension-free transobturator tape procedure. No relationship was demonstrated between postoperative success rates and VLPP.

The relationship between bladder tumors and Schistosoma haematobium is well known, but only sporadic cases of bladder infection due to Schistosoma mansoni have been reported. In this case, a 48-year-old woman with macroscopic hematuria, dysuria and a palpable abdominal mass was investigated. Ultrasound showed a large exophytic mass in the bladder. Transurethral resection of the bladder revealed viable eggs of Schistosoma mansoni. The patient was treated clinically with oxamniquine and surgery was performed to resect the large mass. This case shows that schistosomiasis Mansoni in the bladder can simulate bladder cancer.

É bem conhecida a relação entre tumor vesical e Schistosoma haematobium, porém somente casos esporádicos de infecção vesical por Schistosoma mansoni foram relatados. Neste caso, uma mulher de 48 anos com hematúria macroscópica, disúria e massa abdominal palpável foi investigada, ultra-sonografia mostrou uma grande massa exofítica na bexiga. A ressecção transuretral de bexiga evidenciou ovos viáveis de Schistosoma mansoni. A paciente foi tratada clinicamente com oxaminiquine e uma cirurgia foi realizada para ressecar a grande massa. Este caso mostra que a esquistossomose mansônica vesical pode simular um câncer vesical.

Introduction: The use of protease inhibitors, mainly the indinavir, drug recently introduced for the treatment of patients with the human immunodeficiency virus (HIV), has shown formations of crystals and urinary calculi as side effects. Surch conditions are found in 4 percent of patients using indinavir. Case Report: An HIV positive 32 years old male patient taking indinavir and AZT is presented. During treatment, the patient presented left flank pain and left uretero-hydronephrosis at renal ultrasound. Retrograde pyelography showed an image compatible with ureteral calculi. Six month later the patient presented for consultation and an intravenous pyelography and renal ultrasound were normal. Probably, the calculous had passed spontaneously. Conclusions: The benefits of the protease inhibitors for HIV positive patients are enormous and their use are rapidly increasing. Thus, physicians should be aware of this benign complication. Most of these cases are benign and the treatment should be analgesia and oral and parenteral hydration. Patients using indinavir must be advised to maintain adequate hydration
