Background. Acute renal failure (ARF) in the postoperative period increases the risk of complications and death. Estimating the risk of ARF prior to surgery is particularly important, because it allows modifying the treatment in high-risk patients.Objective: to develop prognostic models for evaluating the risks of ARF in patients undergoing resection of a solitary kidney by measuring preoperative parameters.Materials and methods. The study included 136 patients with tumors in a solitary kidney that underwent surgical treatment in the N.N. Alexandrov National Cancer Center of Belarus in the last 16 years.Results. Biochemical blood tests demonstrated that 28 patients (20.6 %) had ARF in the early postoperative period. The multivariate model for assessing the risk of ARF included the following three covariates: tumor size, multifocality, and serum potassium level. We identified the cut-off points of tumor size (3.6 and 5.2 cm) and potassium level (4.4 and 4.8 mmol/L) that ensured maximum predictive accuracy. Using the multivariate model, we developed a nomogram that allows graphical calculation of the ARF probability in the postoperative period by measuring preoperative parameters.Conclusion. Our model enables preoperative assessment of the risk of developing ARF after resection of a solitary kidney with an accuracy (С-index) of 85.1 % (95 % confidence interval: 79.3–89.7 %).

209 Background: Ascites develops in a subset of patients with PAC at presentation or as the disease advances. Limited data exist on the prognostic importance of malignant ascites in PAC. Our hypothesis is that this information will provide an understanding of the natural history and facilitate management decisions. Methods: We conducted a retrospective analysis of N = 180 patients treated at Memorial Sloan Kettering Cancer Center diagnosed between January 1, 2009 and December 31, 2014, with PAC and ascites either at presentation or which developed during the disease course. Results: For the 180 patients, overall survival was 15 months. Time from diagnosis to ascites presentation was 11 months and survival time after ascites development was 4 months. Of 62 patients (34%) who had ascitic fluid analyzed, N = 36 (58%) had positive cytology, N = 51 (82%) patients had a serum ascites albumin gradient (SAAG) ≥ 1 and N = 11 (18%) had SAAG < 1.1. Sixty-four (36%) of patients had their ascites managed solely by serial paracenteses. A total of 116 patients required a catheter, from these, N = 108 (93%) had a Tenckhoff catheter, N = 4 (3%) Pleurx catheter, N = 3 (2%) Pigtail catheter and one (1%) a Denver catheter. Eight (4%) patients required two catheters to be placed and N = 6 (3%) Tenckhoff catheters had to be removed. Main observed complications: spontaneous bacterial peritonitis in N = 7 (11%) of patients managed with paracenteses vs. N = 34 (19%) who had a catheter placed, catheter malfunction in N = 8 (4%), acute renal failure in N = 6 (3%). After ascites development N = 79 (44%) of patients received active therapy and N = 101 (56%) patients were managed with supportive care alone. Conclusions: In patients with PAC the presence of ascites is a poor prognostic factor. Serial paracenteses and indwelling catheters are common methods used for alleviating patients’ discomfort. The complication rate was higher with indwelling catheters, primarily associated with infections (e.g. bacterial peritonitis) with low rates of complications occurring related to catheter malfunction, acute renal failure or bowel perforation.

The insertion of indwelling ureteric stents is a routine procedure in urology practice. Complications secondary to the insertion of these stents have also increased, such as stent encrustation, stent fragmentation, stone formation, and recurrent urinary tract infections. Knot formation within the renal pelvis or in the coiled portion of the ureteral stent is an extremely rare condition, with less than 15 cases reported in literature. The authors report a rare case of knotted stent, complicated by an obstructive acute renal failure and urosepsis, in a patient with a solitary functioning kidney.
