Background: Elective scrotal surgery is associated with a high rate of postoperative complications. There is no specific recommendation for postoperative care., Aim: We investigated whether support underwear has an impact on postoperative complications and quality of life., Materials and Methods: From July 2020 to November 2021, patients with prior elective scrotal surgery were randomized into the intervention group "support underwear" or the control group. In addition to patient characteristics, intraoperative and postoperative findings were documented. The primary endpoint comprised postoperative complications. Secondary endpoints were prolonged length of hospital stay, emergency visits, unplanned readmissions, increased use of analgesics, and quality of life, which was recorded using the EQ5D (European Quality of Life 5 Dimensions) questionnaire preoperatively, on day 1 and 4 weeks postoperatively., Results: Data from 50 patients were analyzed. The mean age was 46.7 years (standard deviation [SD] 18.6). Inguinal surgery with/without orchiectomy (52%), hydrocele resection (22%), or ligation of varicocele (14%) were performed most frequently. The mean operating time was 62.8 min (SD 35.2); length hospital stay was 2.6 days (SD 1.2). In all, 20% of the patients suffered a postoperative complication. Type of surgery was significantly associated with postoperative complications (p = 0.01) and unplanned readmission (p = 0.04). Regarding biometric and perioperative data, there were no significant differences between the interventional group (n = 27) and control group (n = 23)., Conclusion: A nonnegligible number of complications occurs after elective scrotal surgery. Complications affects quality of life up to 4 weeks after the surgery. Postoperative care with support underwear does not appear to affect the postoperative complication rate, but it positively influences the quality of life in patients with scrotal access., (© 2022.

Purpose: To test the value of preoperative and postoperative cystatin C (CysC) as a predictor on kidney function after partial (PN) or radical nephrectomy (RN) in renal cell carcinoma (RCC) patients with normal preoperative renal function., Methods: From 01/2011 to 12/2014, 195 consecutive RCC patients with a preoperative estimated glomerular filtration rate (eGFR) > 60 ml/min/1.73m 2 underwent surgical RCC treatment with either PN or RN. Logistic and linear regression models tested for the effect of CysC as a predictor of new-onset chronic kidney disease in follow-up (eGFR < 60 ml/min/1.73m 2 ). Moreover, postoperative CysC and creatinine values were compared for kidney function estimation., Results: Of 195 patients, 129 (66.2%) underwent PN. In postoperative and in follow-up setting (median 14 months, IQR 10-20), rates of eGFR < 60 ml/min/1.73m 2 were 55.9 and 30.2%. In multivariable logistic regression models, preoperative CysC [odds ratio (OR): 18.3] and RN (OR: 13.5) were independent predictors for a reduced eGFR < 60 ml/min/1.73m 2 in follow-up (both p < 0.01), while creatinine was not. In multivariable linear regression models, a difference of the preoperative CysC level of 0.1 mg/dl estimated an eGFR decline in follow-up of about 5.8 ml/min/1.73m 2 . Finally, we observed a plateau of postoperative creatinine values in the range of 1.2-1.3 mg/dl, when graphically depicted vs. postoperative CysC values ('creatinine blind area')., Conclusion: Preoperative CysC predicts renal function impairment following RCC surgery. Furthermore, CysC might be superior to creatinine for renal function monitoring in the early postoperative setting., (© 2021. The Author(s).)
