Predictors of pain resolution after varicocelectomy for painful varicocele

Varicocelectomy is a management option for patients with painful varicocele. In this study, we assessed the effectiveness of varicocelectomy for painful varicocele and examined the factors that might be predictive of outcome. All patients who underwent a varicocelectomy for pain between February 2007 and July 2009 were included. A review of patient medical records was conducted; patient age, body mass index (BMI), grade, location of the varicocele, testicular volume, duration and quality of the pain (dull, dragging, throbbing or sharp) and surgical technique (inguinal versus subinguinal) were documented. All parameters were compared with the resolution of pain (complete, partial or failure). We followed up on 53 of 104 patients (51.0%). Complete postoperative resolution of pain was reported by 28 patients (52.8%), whereas 22 (41.5%) reported partial resolution. Only three patients (5.7%) reported failure. No relationship was observed between postoperative pain resolution and age, BMI, grade of varicocele, location of varicocele, ipsilateral testicular hypotrophy, quality of pain or surgical technique. The duration of pain before surgery was the only factor that correlated with postoperative pain resolution (univariate, P=0.004; multivariate, P=0.002). Our results indicate that varicocelectomy is an effective treatment for painful varicocele in properly selected patients, and that duration of pain before surgery may be predictive of outcome.
