Objective: This study analyzed the total symptom score, irritative and obstructive domains of IPSS questions regarding quality of life and the urodynamic diagnosis in 400 men with LUTS.Materials and Methods: Four hundred consecutive male patients were prospectively enrolled after being submitted to full urodynamic evaluation and IPSS. Obstructed and non-obstructed patients were compared regarding the symptoms score and quality of life. Results were assessed through Wilcox, ANOVA and Student-t tests.Results: 80.2% were diagnosed as urodynamically obstructed of which 42.4% presented detrusor instability in the filling phase. In obstructed patients there were no statistical difference concerning obstructive or irritative questions from IPSS (p = 0.50). It was not possible either to predict which patients presented detrusor instability based on the questionnaire (p = 0.65). Out of seventy-nine cases unobstructed (19.8%), 65.4% revealed detrusor instability. These cases could not be distinguished from all obstructed men based on the clinical questions measured by IPSS (p = 0.87). Obstructive and irritative questions did not present different indexes than obstructed cases (p = 0.63). Subjective quality of life index did not discriminate obstruction nor it could predict detrusor instability in both groups.Conclusion: Clinical symptoms and quality of life index measured by the IPSS as well as its obstructive and irritative domains do not have discriminating power to predict the presence of infravesical obstruction in males with LUTS, demanding objective tools to demonstrate obstruction.
Sling operations are a safe and efficacious option to treat SUI, however, the results can vary according to the technique employed. Shorter efficacy and fewer complications are observed in vaginal wall sling operations, while durable results, but with a higher rate of voiding dysfunctions compromising the long-term clinical satisfaction may be observed after excessive urethral suspensions, as in fascial sling suspension.
Introduction: An alternative technique for kidney transplantation is presented for patients in whom the use of pelvic vessels is precluded. Patients and Methods: Of 482 cases of kidney or pancreas-kidney transplants, 4 were unsuited to heterotopic grafting, 1 due to multiple operations in the fossae and the 3 others due to extensive vascular occlusive disease. The patients were studied preoperatively by magnetic resonance angiography, which revealed extensive occlusive disease of the distal aorta and/or iliac vessels. Results: The patients received kidneys from living related donors as a third or second transplant opportunity in the orthotopic position (2 cases). Gross dissection of the aorta revealed a thickened wall, impeding direct anastomoses between the recipient’s arteries and the donated organ. After a termino-lateral Dacron graft to the aorta, all cases were stented for uretero-uretero anastomosis. Recovery with respect to the renal graft was uneventful for all cases. Conclusions: Alternative direct grafting from the aorta represents a viable and easy way to perform kidney transplants in patients unsuited to the heterotopic approach.
Aims: Involuntary Detrusor Contraction (IDC) may alter therapeutic plans; therefore, urodynamic demonstration (UD) is pivotal. We explore if same session repetitions enhance its demonstration and minimize false-negative results. Methods: Two hundred fifty two women (mean age 47 ± 5.7) had 4 full repetitions of UD with the last round filled with 4°C fluid (Ice-water test). IDC was diagnosed if with at least 3 cm H2O after artifacts were ruled out. Results: 44.4% of the cases showed IDC in the first round of the exam but it could be demonstrated in 88.5% of the women if 4 rounds are taken into account. Only 2 cases showed IDC exclusively in the first round. Nine cases (3.5%) showed IDC in the first round and only on Ice-test, while all other IDC-detected cases revealed it in scattered patterns along the repetitions. Likewise, IDC detection on the second, third and fourth rounds varied widely and unpredictably, many failing to show a consistent pattern of presentation after its detection. IDC wave amplitude did not show any correlation to the detection. Conclusions: Urodynamic repetition is a necessary procedure where IDC is important to demonstrate, as its false-negative rate is high and its unpredictable pattern of detection may be improved by repetition.
CONTEXT: Antibiotic prophylaxis in transurethral resection of the prostate is a regular practice in urology. However, its prophylactic effect can be questioned when the antiseptic surgical technique is used. Nonetheless, urine culture-oriented antibiotic therapy is the gold standard for avoiding improper medication usage and bacterial resistance. OBJECTIVE: To study the efficacy of antibiotic usage in patients with negative urine cultures, who were submitted to transurethral resection of the prostate. TYPE OF STUDY: Prospective open labeled study. SETTING: Tertiary care referral hospital PARTICIPANTS: 124 consecutive patients, who were randomly divided into two groups to receive antibiotic prophylaxis or not. MAIN MEASUREMENTS: Cultures from meatus, urine, irrigation and antiseptic fluid, and prostate tissue chips, were compared and analyzed for bacterial sensitivity to the antibiotic used, according to the surgeon's personal criteria. McLennan's test was used for statistical analysis. RESULTS: No statistically significant difference regarding clinical evolution was found between the groups that received or antibiotics or not. Statistical significance was found regarding the occurrence of positive urine cultures during the postoperative period for those not receiving antibiotics, but not in relation to fever, prostate chip culture or bacteremic episodes. Sixty-eight subjects (57.1%) presented positive prostatic tissue culture. There was no specific correlation between the recovered bacteria from the meatus, prostatic tissue chip and urine and the spectrum of the administered antibiotic. Six cases showed the same bacteria in the urine and prostatic tissue chip. Only fifteen cases (25%) in the antibiotic group showed the desired sensitivity directed to the collected bacteria. CONCLUSIONS: Antibiotic prophylaxis for patients whose urine is sterile is debatable in patients who are candidates for transurethral resection of the prostate. Most of the time, the antibiotic agent used is not specific for any of the bacteria recovered from the various sources analyzed.
Introduction: The prevalence of bladder outlet obstruction in men has been overestimated leading to improper clinical results after transurethral resection of the prostate. Patients and Methods: 3,830 consecutive male cases submitted for urodynamic evaluation were prospectively analyzed using a Schaefer nomogram. The prevalence of detrusor overactivity and the occurrence of obstruction were prospectively studied using standardized urodynamic practice. Results: Infravesical obstruction was diagnosed in 44.8% of the studied population: 0.7% of the obstructed cases were obstructed at the sphincter zone and 7.9% showed obstruction as a high-pressure, high-flow-rate pattern. Detrusor overactivity was demonstrated in 73.9% of the obstructed cases and in 22% of the unobstructed. Older patients (>60 years) seemed more likely (odds ratio: 2.8) to present detrusor overactivity, but at the same time showed less frequent obstruction. The oldest subjects (>80 years) showed a lower prevalence of obstruction, although overactive bladder was a common finding. Conclusion: Infravesical obstruction is less frequent than previously stated. The common assumption that obstruction is the cause of lower urinary tract symptoms in older men is wrong. Older men are more likely to suffer from detrusor overactivity resulting from lower urinary tract symptoms rather than infravesical obstruction. Urodynamic studies seem to be crucial for a proper diagnosis in men considered candidates for surgical treatment.
OBJETIVO: Analisar a resposta bioquímica nas variáveis volume prostático, valor do antígeno prostático específico (PSA), escores de Gleason, estádio, risco da doença e hormonioterapia. MATERIAIS E MÉTODOS: No período de fevereiro de 1998 a julho de 2001, 46 pacientes com câncer de próstata foram tratados com radioterapia, numa combinação de teleterapia e braquiterapia de alta taxa de dose (BATD). A idade variou de 51 a 79 anos (média de 66,4 anos). O estádio T1c foi o mais freqüente: 30 (65%). O escore de Gleason era abaixo de 7 em 78% dos pacientes. O PSA variou de 3,4 a 33,3, estando abaixo de 10 em 39% das vezes. O volume prostático médio foi de 32,3 cc. Um total de 28% dos pacientes recebeu hormonioterapia. A dose de teleterapia variou de 45 a 50,4 Gy, associada a quatro frações de BATD de 4 Gy. RESULTADOS: O seguimento variou de 6 a 43 meses. Quatro pacientes perderam seguimento e quatro morreram (um por doença). Dos 39 pacientes analisados, 76% apresentaram PSA menor que 1,5. Nenhuma das variáveis analisadas foi estatisticamente significante (p > 0,05) com relação ao controle bioquímico. CONCLUSÃO: A utilização de BATD foi eficiente no tratamento do câncer de próstata e, neste estudo, as variáveis consideradas como fatores prognósticos não interferiram no controle bioquímico.
