[Current trends in the method used for urine derivation after radical cystectomy for muscle-invasive bladder cancer].

Bladder cancer ranks 7th in the world among all malignant tumors in men and 11th in both sexes. Radical cystectomy is the gold standard of muscle-invasive bladder cancer treatment in most countries of the world. A large number of fundamentally different options for urine derivation is developed. Therefore the choice of the method of urine derivation is one of the most important and difficult in the treatment of such patients. This review covers current international articles on this topic for 2015-2018.

[Radical cystectomy: therapeutic aspects of preoperative and early postoperative management].

AIM: to improve the results of radical cystectomy by optimization of patient preparation for surgery and early postoperative care. MATERIALS AND METHODS: A total of 136 patients who underwent radical cystectomy and either orthotopic ileal neobladder or ileal conduit formation were included in the study. Brikkers operation was performed in 92 patients (76% men and 24% women) aged from 39 to 83 years, while in 44 patients (97.7% men, 2.3% women) aged from 32 to 75 years the Studer ileal neobladder was created. All patients underwent preoperative comprehensive examinations in order to determine type and extent of surgical treatment. RESULTS: A complication rate after radical cystectomy with urine derivation using bowel segment was 49.2%. Mortality rate in early postoperative period was 3.9%. CONCLUSION: An algorithm of postoperative care after radical cystectomy with formation of either orthotopic neobladder or ileal conduit and consideration of comorbid status and preparation which we have used in clinical practice was developed. According to the results, after implementation of algorithm of management in preoperative and early postoperative period a decrease in complications and mortality rate has been found.

[The incidence of malignant transformation of renal cysts of category 1, 2, and 2F by the BOSNIAK classification into multilocular cystic renal cell carcinoma].

RELEVANCE: Renal cysts remain the most common of benign renal lesions, but current literature is lacking large observational studies on the incidence of their malignant transformation. AIM: To assess the incidence of malignant transformation of renal cysts of category 1, 2, and 2F by the Bosniak classification into multilocular cystic renal cell carcinoma. MATERIALS AND METHODS: From January 2009 to December 2017, 177 patients with renal cysts of category 1 (n=50), 2 (n=74), and 2F (n=53) underwent laparoscopic decortication. In 10 cases, post-operative histological and immunohistochemical studies revealed foci of grade 1 (pT1a) multilocular cystic renal cell carcinoma. RESULTS: Foci of grade 1 (pT1a) multilocular cystic renal cell carcinoma were detected in 10 (5.65%) patients (five men, five women, mean age 58.9 years). The incidence of malignant transformation of renal cysts of categories 1, 2, and 2F was 0%, 2.7% (2 of 74 patients), and 15.1% (8 of 53 patients), respectively. Subsequently, all ten patients were submitted to surgical treatment: eight of them underwent a partial nephrectomy, and two received a nephrectomy. During a median of 49.3 (31-72) months follow-up, no metastasis, and recurrence of multilocular cystic RCC were observed. CONCLUSION: A more modern algorithm for managing patients with Bosniak category 1, 2 and 2F cysts need to be developed to establish early surveillance of patients starting with category 1 cysts. Given the low malignant potential of these tumors, they should be treated with organ-sparing surgery.

[Importance of surgery of quick recovery program for surgical treatment of bladder tumors].

The article presents an analytical review of literature outlining the prospects for the use of the program "Surgery of quick recovery" in the surgical treatment of the bladder malignant tumors. The multi-modal program "Surgery of quick recovery" was found to reduce the number of postoperative complications and shorten recovery of patients with bladder cancer.

[Pilot experience in using adjustable suburethral sling in the treatment of anatomic stress urinary incontinence in females].

Adjustable suburethral prolen sling (Agency for Medical Innovations) was set up during surgery via transobturatory approach in 21 females with stress urinary incontinence (SUI). Mean age of the patients was 58.5 years (32-76 years). Only 3 (14%) women failed to retain urine on postoperative day 1, the other 18 of 21 (86%) women no longer showed SUI. Obstructive urination was observed in 4 of 21 (19%) patients, residual urine was present in 3 of these 4 patients (120, 170 and 220 ml). Correction of the sling position was made in early postoperative period in 7 (33.3%) patients. Under local anesthesia of the paraurethral channels with 0.5% novocain solution, the sling was displaced in the direction from the urethra to obturatory opening in 3 women with residuary SUI, from the urethra to the vagina - in 4 women. After regulation of the sling position all the patients retained urine and had no residual urine after urination. Thus, the suburethral prolen sling the position of which can be adjusted in early postoperative period is an effective method of treating females with anatomic SUI.
