Abstract
Background:
Orchialgia is not an uncommon complaint among men with varicocele, but postvaricocele embolization–related testicular pain has not been widely investigated. This study evaluates the phenomenon of postvaricocele embolization pain (PVEP) syndrome and examines the current strategies to treat this unusual complication.
Methods and materials:
A prospectively collected database of patients with PVEP who presented to a tertiary center was analyzed between January 2011 and January 2020 following internal ethics approval. Patient demographics, including other complications related to embolization, analgesic requirements, and pain scores (on a 10-point visual analog score), treatment strategies, Patient Global Impression of Improvement (PGI-I) score and overall satisfaction score (on a 5-point scale), were reviewed. All patients were reviewed for a minimum of 12 months.
Results:
A total of 20 men with a mean age of 33.8 (18–45) years old, presented with PVEP over 10 years. Most men received embolization on an average of 26.6 (18–48) months. The reasons for varicocele embolization include either isolated or combined orchialgia (15 men), subfertility (5 men), and cosmesis (6 men). Eighteen (90%) men underwent microscopic spermatic cord denervation (MSCD) and 2 patients elected for conservative measures. The average pain scores pre-MSCD and post-MSCD were 6.9 (4–9) and 1.4 (0–4) (p<0.001) with a significant reduction in analgesia requirements. Immediate improvement in pain score was reported in all the patients and this persisted at the 12 months review. Most men reported a high satisfaction score (of 4/5) and only one patient reported no change in symptoms after MSCD.
Conclusion:
PVEP is a unique complication and patients should be counseled on the potential risk of persistent orchialgia following embolization for varicocele. The MSCD appears to be an effective treatment option with high success and satisfaction rates.
