Prognostic Factors for the Postoperative Outcome of Penile Venous Surgery for Venogenic Erectile Dysfunction

Abstract Background The aim of this retrospective study was to evaluate commonly used clinical and OCT-morphological parameters, including perifoveal pseudocysts, as prognostic factors for postoperative outcome after macular hole surgery in a retinal referral clinic in North Rhine-Westphalia, Germany. Methods and material This was a retrospective analysis of all patients who underwent surgery because of idiopathic MH between 2011 and 2017 in Augenklinik Tausendfensterhaus, Duisburg, Germany. Statistical evaluation of clinical and OCT-based parameters, including the areas of intraretinal pseudocysts, was conducted. The main statistical outcomes were surgical success and visual acuity. Only parameters with a highly significant correlation to the outcome parameters (postoperative visual acuity (VA); surgical success) in univariate analysis were entered in linear and logistic regression analyses. Results A total of 189 eyes of 178 patients (71.4% female; mean age 67.5 ± 8.2 a) who underwent surgery because of MH were included. The overall closure rate was 86.8%. The mean best corrected VA increased from 0.7 ± 0.3 logMAR before surgery to 0.5 ± 0.3 logMAR (p < 0.0001). While several clinical and OCT-based parameters as well as calculated indices showed a significant correlation with the outcome measures, the regression analysis showed that the minimum linear diameter was the only parameter that both predicted surgical success (p = 0.015) and was correlated with postoperative VA (p < 0.001). Conclusion The minimum linear diameter serves as an easily assessed prognostic factor with the best predictive properties. This result is of great importance for clinical practice, as it simplifies the postsurgical prognosis.

Venous Function

SummaryOur goal was to document changes in venous drainage function ΔV and venous refill times to and th achieved with venous surgery and compare them with preoperative measurements acquired using a variety of venous function tests. Preoperative measurements were performed with two pressure cuffs to predict postoperative outcome; they were compared with actual postoperative measurements made without a pressure cuff. In addition we also analyzed whether the postoperative improvement in venous haemodynamics was correlated with an improvement in clinical findings and symptoms. Patients, methods: 64 patients (14 men and 50 women) were enrolled into the study. Inclusion criteria were Doppler sonographic evidence of insufficiency of the saphenous veins and impaired venous haemodynamics, which form the medical indication for venous surgery. Before and after surgery a variety of diagnostic tests of venous function were carried out simultaneously with the patient in a seated position and performing dorsal extensions: mercury strain gauge plethysmography (MSGP) at the forefoot and calf, phlebodynamometry (PDM), light reflection rheography (LRR), digital photoplethysmography (DPPG) with Elcat measuring head and with Laumann Elcat measuring head, universal light reflection plethysmography (ULP). Results: All the examined methods are suitable for monitoring progress and evaluating therapeutic success after the selective surgical removal of insufficient vein segments. All examination methods showed that refill times t0 and th were significantly improved 6 weeks after venous surgery. The postoperative results of ΔV, t0 and th were most reliably predicted by MSGP (forefoot). ΔV, to and th values determined with MSGP at the calf differed significantly from those acquired with PDM, so MSGP (calf) should not be used for preoperative screening. Conclusions: A close correlation between improvement of clinical symptoms and improvement in venous haemodynamics was found. Selection of the suitable preoperative measurement method makes it possible to accurately predict postoperative outcome.
