Summary

Cancer of the cervix causes internal, external compression or both of the upper urinary tract in 50-60%of patients in advanced stages. Retrograde stenting is the most widely used technique for desobstruction of the upper urinary tract in urology practice. Diversion of urine flow is an alternative, achieved by nephrostomy of one or both kidneys.We studied retrospectively 33 women with upper urinary tract obstruction caused by carcinoma of the uterine cervix operated on between March 2014 and March 2015 in the urology clinic at the University Hospital in Pleven, Bulgaria. Apercutaneous nephrostomy (PNS) was placed in 17 patients, and 11 patients hadaretrograde catheterization with ureteral stent type JJ. Five patients were treated with both methods. Placement ofa JJstent was the first choice procedure for all patients since it providesabetter quality of life. PNSimproves renal function faster than retrograde JJstenting. Therefore, the first method of choice for patients with an untreated primary cervical, uterine cancer is the placement of PNS. Retrograde JJstenting is the method of choice in patients who undergo surgery and radiation therapy withoutarelapse of the disease.

Summary

Prostate cancer (PC) is the most common type of cancer in men inanumber of countries. The choice of surgical technique for radical prostatectomy (RP) concerns both patients and urologists. The choice is not easy to make, since data is still limited due to the lack of large multicentric randomized research trials. For three years (2011-2014), 244 patients with limited prostate cancer were operated in the Urology Clinic of the University Hospital in Pleven. Robot-assisted radical prostatectomy (RARP) was performed on 35 patients (14%), open retropubic radical prostatectomy (ORP) - on 199 patients (81%), and laparoscopic RP - on 12 patients (5%). The preoperative and post-op results from the first two groups were compared. For the follow-up period of 12 months, functional results in 82 patients of the ORPgroup were compared to the results in the 35 patients of the RARPgroup. The operative time was significantly longer in the RARPgroup, and blood loss was lower. The catheter stay was shorter in patients with RARP. The percentage of significant postoperative complications was 0%in the patients with RARPand 3%in the patients with an ORP. RARPpatients demonstrated better continence: 91%vs. 87%and erectile function46%vs.40%at 12 months.
