RESUMO

PURPOSE: To evaluate the necessity of chronic alkali therapy in non-complicated orthotopic ileal neobladders with normal renal function. MATERIALS AND METHODS: This is a prospective study that included 200 male patients who underwent radical cystectomy and ileal W neobladder for invasive bladder carcinoma between January 1993 and December 2013. The studied patients included 100 consecutive patients who were maintained on regular alkali therapy since surgery and 100 consecutive patients who stopped the use of alkali treatment after initial 3 months postoperative with minimum postoperative observation time of 1 year. All patients had satisfactory function of the reservoirs with normal upper tract. The patients were subjected to blood analysis for creatnine, electrolytes, pH and bicarbonate and urine chemical analysis. The study also included 40 healthy male age-matched volunteers who served as a control group. RESULTS: Both groups were comparable as regard age, BMI, follow-up period and surgical technique. There were no significant differences between both groups as regard serum creatnine, electrolytes blood pH and bicarbonate and the mean values were within normal range; however, the neobladder patients are still toward the acidotic side in comparison to healthy volunteers. Also there were no significant differences between both groups of patients as regard urine pH and excretion of electrolytes, calcium, phosphorus and creatnine. CONCLUSION: Patients with non-complicated ileal neobladders with normal upper tract who were not maintained on alkali prophylaxis for long period have a compensated acid base status. Therefore, the prolonged alkali prophylaxis is not mandatory.

RESUMO

OBJECTIVE: To characterize the standard physical, chemical, and microscopic characteristics of urine in patients with noncomplicated orthotopic ileal neobladders. MATERIALS AND METHODS: This is a prospective study that included 100 male patients who underwent radical cystectomy and ileal neobladder between 1993 and 2013. All included patients were in a good health and having satisfactory function of the reservoirs with normal upper tract with a minimum 1-year postoperative follow-up. We excluded patients with oncological failure, those with diversion-related complications, those who were maintained on clean intermittent catheterization, or those who have symptoms of urinary tract infection. Patients with medical diseases that may affect urine properties (eg, diabetes mellitus) or receiving special medications (eg, diuretics, alkali therapy, or antibiotics) were also excluded. The patients were subjected to urine analysis, blood chemistry, pH, and blood gases; the results were compared to a control group of 40 normal male volunteers. RESULTS: Urine analysis in diverted patients showed higher urine pH than in control group but it is still acidic. Pyuria, proteinuria, hematuria, and positive culture were significantly higher in diverted patients. The chemical analysis showed lower urinary calcium, phosphorus, and creatinine contents in diverted patients than in the control group. Serum creatinine was significantly higher in diverted patients, whereas blood pH and bicarbonate were lower, but these values are within normal. CONCLUSION: Urine from uncomplicated orthotopic ileal reservoirs is acidic. Pyuria, proteinuria, minor degrees of microscopic hematuria, and positive nitrite reaction are normal findings. We also have normal findings for lower urinary calcium, phosphorus, and creatinine contents in patients.
