Given study was aimed to research a role of kinetic performance of PSA in selection of the patients for conduction 11C-choline PET/CT in order to reveal local recurrences in patient with prostate cancer after radiation therapy (RT) and radical prostatectomy (RP). The study included 185 patients with histologically distinctive prostate cancer and biochemical signs of tumor recurrence after RP (61 patients) or RT (124 patients). All the patients were examined using 11C-choline PET/CT in order to detect local relapses. Calculation of growth rate of the PSA level and PSA doubling time were made. According to results of 11C-choline PET/CT, recurrences of prostate cancer were detected in 124 out of 185 (65%). There were 22 patients out of 61 (36%) after RP and there were 102 patients out of 124 (82%) after RT. It was stated a correlation between PSA rates, growth rate of PSA level and presence or absence of relapse according to PET/CT results. PSA level and growth rate of PSA were indicated as the most significant predictive signs, which could influence on the selection of the patients for conduction of 11C-choline PET/CT in relation to detection of local recurrence after RT and RP.

The authors showed the result of complication treatment of lower urinary tracts in 128 patients with localized prostate cancer. The patients underwent radical prostatectomy. Urinary discomforts included enuresis, urinary incontinence in postoperative period. Abnormalities of urine outflow due to urethral stricture were revealed in 6 (4,6%) patients by the 6 month after operation. These complications required surgical treatment. Urinary incontinence was noted in 20 (15,6%) patients in this period. It was stressful urinary incontinence in 16 (12,6%) and urgent - in 4 (3%). Patents with stressful urinary difficulty were advised to use the conservative treatment (pelvic floor muscle training and electrostimulation), but in case of inefficiency - surgical treatment.

Forty three patients with unsatisfactory outcomes of surgical treatment of benign prostatic hyperplasia (BPH) were examined urodynamically. Thirty five patients complained of daily and nocturnal pollakiuria, incomplete evacuation of urine from the bladder, imperative voiding. Eight patients had postoperative enuresis. Seventeen control patients had satisfactory surgical results. The urodynamic findings showed that postoperative dysuria was caused by detrusor pathology: detrusor hyperactivity (n = 27, 62.8%), contractile hypoactivity (n = 4, 9.3%), infravesical obstruction (n = 4, 9.3%). Diuresis patients had low maximal cystometric capacity of the urinary bladder, detrusor hyperactivity was diagnosed in 5 (62.6%) patients. Enuresis patients had also very low indices of urethral profilometry characterizing function of the sphincter. The urodynamic examination detected true stress urine incontinence in 3 enuresis patients due to sphincter impairment. Five patients had enuresis of mixed nature. Thus, urodynamic examination of patients with unsatisfactory results of surgery determined cause of dysuria. Accurate diagnosis of characteristics and causes of lower urinary tracts dysfunction decides choice of adequate therapeutic policy.
