ABSTRACT Introduction Scrotoplasty has become a common practice during insertion of penile prosthesis, improving patient perception of penile length. Previous reports on scrotoplasty outcomes have only focused on the perceived benefits. The risk of wound complications after scrotoplasty is unknown. Aim Identify wound complications and associated risk factors of scrotoplasty with insertion of penile prosthesis. Methods A retrospective review of a single-surgeon series (T.S.K.) of patients who underwent scrotoplasty with initial insertion of inflatable penile prosthesis (IPP) was performed from 2009–2014. Surgical outcomes and wound complications after scrotoplasty were examined, along with patient information, including basic demographics, medical comorbidities, and perioperative data. Main Outcome Measures Studied outcomes included rate of wound complications after scrotoplasty and IPP insertion and identification of risk factors for wound dehiscence. Results Of the 103 scrotoplasties performed during the study period, a total of 15 had mild, moderate, or major wound dehiscence. Of these 15 cases, 9 had mild dehiscence and 5 cases had moderate dehiscence and required stitches to be placed in clinic to reinforce the closure. 1 patient had a major dehiscence requiring a return to the operating room for a washout, with exchange of IPP to malleable prosthesis. Multiple risk factors for wound dehiscence were found, including diabetes (odds ratio 6.1, CI 1.5, 25.0, P = .0129) and scrotoplasty technique (odds ratio 4.9, CI 1.2, 8.6, P = .003). Other examined variables, including patient age, Peyronie’s disease, hypertension, intraoperative penile modeling, smoking, and device manufacturer, were not associated with wound dehiscence. Clinical Implications Patients with diabetes and scrotoplasties performed via V-Y plasty are more likely to experience wound dehiscence. Strengths & Limitations Strengths include a single surgeon, thus lending continuity of skill and technique, a consecutive series, and 100% short-term follow-up. Limitations include retrospective design, single institution series, and lack of long-term follow-up. Conclusion Although scrotoplasty can improve patient satisfaction with IPP, scrotoplasty can lead to increased patient morbidity. Diabetic patients are at increased risk for wound complication after scrotoplasty.

Nutcracker syndrome (NS) refers to symptomatic compression of the left renal vein (LRV) between the abdominal aorta and superior mesenteric artery with potential symptoms including hematuria, proteinuria, left flank pain, and renal venous hypertension. No consensus diagnostic criteria exist to guide endovascular treatment. We aimed to evaluate the specificity of LRV compression to NS symptoms through a retrospective study including 33 NS and 103 control patients. The size of the patent lumen at point of compression and normal portions of the LRV were measured for all patients. Multiple logistic regression analyses (MLR) assessing impact of compression, body mass index (BMI), age, and gender on the likelihood of each symptom with NS were obtained. NS patients presented most commonly with abdominal pain (72.7%), followed by hematuria (57.6%), proteinuria (39.4%), and left flank pain (30.3%). These symptoms were more commonly seen than in the control group at 10.6, 11.7, 6.8, and 1.9%, respectively. The degree of LRV compression for NS was 74.5% and 25.2% for controls (p < 0.0001). Higher compression led to more hematuria (p < 0.0013), abdominal pain (p < 0.006), and more proteinuria (p < 0.002). Furthermore, the average BMI of NS patients was 21.4 and 27.2 for controls (p < 0.001) and a low BMI led to more abdominal pain (p < 0.005). These results demonstrate a strong correlation between the degree of LRV compression on imaging in diagnosing NS.
