The Effects of Diuresis, Duration of Dialysis and Age on Lower Urinary Tract Function in Urologically Healthy Male Patients on the Waiting List for Kidney Transplant.

PURPOSE: This work investigated the effects of diuresis, duration of dialysis and age on lower urinary tract function in urologically healthy males on the waiting list for kidney transplant. MATERIALS AND METHODS: The study included all men who had kidney transplants at our centre between January 2009 and December 2014 who had normal urological findings prior to inclusion on the list. Diuresis, the duration of haemodialysis, age, and parameters of function of the lower urinary tract as determined by filling and voiding cystometry were evaluated. RESULTS: The study included 127 men (median age, 59 years; median diuresis, 250 mL; median duration of dialysis, 469.5 days). We found that greater diuresis was accompanied by significantly higher FDV, FDV/Cmax, NDV,Cmax and compliance and by significantly lower Pdet.max, PdetQmax and BOOI. Longer duration of dialysis was accompanied by significantly lower FDV, NDV and Cmax, compliance and Qmax.p and with significantlyhigher Pdet.max, PdetQmax and BOOI. Older age was associated with significantly higher Pdet.max and with significantly lower compliance. Worsening of the basic parameters of the storage function of the lower urinary tract occurred when diuresis decreased to 500-750 mL, when the duration of dialysis was one year and when patients were older than 54 years. CONCLUSION: In healthy male patients on the waiting list for kidney transplant, there were connections between the occurrence of dysfunctions of the lower urinary tract and diuresis, duration of dialysis and age. Patients should be monitored for dysfunctions of the lower urinary tract before and after transplantation.

The incidence of subclinical forms of urogenital tuberculosis in patients with pulmonary tuberculosis.

The aim of our study was to determine whether patients with pulmonary tuberculosis may have subclinical forms of urogenital tuberculosis. Between 2011 and 2012, a prospective study was conducted. Basic demographic parameters were recorded and the following investigations were performed: direct bacilloscopy of sputum, evaluation of affected lung fields and presence of cavities on chest X-ray, Mantoux tuberculin skin test II, and interferon gamma release assay. Culture and molecular methods for Mycobacterium tuberculosis in urine were performed. In cases with a positive urine test, an ultrasound examination, computed tomography scan of the abdomen, and endoscopy of the urinary tract were performed. A total of 102 patients (75 men and 27 women) were included in the study, with a median age of 46.8 years. Subclinical forms of urogenital TB were detected in 7 patients; 5 by molecular methods, 1 by urine culture, and 1 with both methods The presence of subclinical forms of genitourinary TB was found in 4 patients without and 3 patients with findings on imaging methods corresponding to TB. A significant number of patients with pulmonary tuberculosis may simultaneously have subclinical forms of urogenital TB.
