Testicular Pain Following Laparoscopic Donor Nephrectomy: An Underreported Complication

Introduction: Testicular pain (TP) after laparoscopic donor nephrectomy (LDN) is a relatively underreported complication. This study aimed to investigate the incidence, characteristics, and factors associated with ipsilateral TP after left-sided LDN. Materials and Methods: This study prospectively collected baseline data and surgical details for all patients who underwent left-sided LDN during the study period. Each patient underwent scrotal ultrasonography 1 month postoperation. Donors were categorized by the level of gonadal vein ligation (level 1 at the renal vein confluence and level 2 at or below the iliac vessel crossing) and the presence or absence of TP. The characteristics of pain and demographics were compared across the groups. Results: Among 61 male patients who underwent left-sided LDN between March 2017 and December 2018, 54.1% (33/61) experienced ipsilateral TP. TP was more frequent in level 2 donors (64.3%) than in level 1 (45.5%), but the difference was not statistically significant (p = 0.141). Most TP occurred within a week (60.6%), was mild (75.8%), and resolved within 3 months (63.7%). The incidence of varicocele and hydrocele was 32.8% and 34.4%, respectively. The occurrence of TP was not significantly associated with the presence of varicocele or hydrocele and other factors. Conclusion: More than half of the male donors who underwent LDN experienced TP. The findings emphasize the importance of discussing this potential complication during preoperative counseling. This study found no significant association between TP and the level of gonadal vein ligation or the presence of varicocele, warranting further investigation into the cause of TP.
