ABSTRACT
Background and Purpose: Etiology of orchialgia or testicular pain after laparoscopic donor nephrectomy (LDN) has been found to be related to injury of the spermatic plexus during gonadal (testicular) vein (GV) or ureteral ligation. This study aimed to evaluate and validate the impact of the level of ligation of GV and ureter in relation to the crossing of iliac vessels (CIV) on incidence of orchialgia.
Patients and Methods: A prospective study was conducted on 70 males who underwent left LDN from January 2008 to December 2010 (group A) to determine the correlation between orchialgia and level of ligation of the GV and ureter with respect to CIV; this revealed that the ligation of the GV and/or ureter above the level of the CIV (level 1, n=40) is less likely to cause orchialgia than ligating them at or below (level 2, n=30). Subsequently, in 45 male patients (group B) for left LDN from January 2011 to June 2013, we ensured that clipping of the ureter and GV be performed above the CIV to validate the above findings. Patients with a history of scrotal pathology or surgical procedure were excluded. One-sided Z-test with pooled variance was used to calculate the sample size.
Results: In group A, orchialgia was seen in 10 (14.3%) patients. The clipping of the ureter and GV at level 2 (orchialgia, n=9) was associated with a significantly higher incidence of orchialgia than clipping them at level 1 (orchialgia, n=1) (P=0.001,95% confidence interval=0.0707 to 0.2471). In group B, 43 patients were finally analyzed, and none had orchialgia.
Conclusion: The level of ligation of the GV and ureter has significant impact on the incidence of orchialgia. Ipsilateral testicular pain in patients with left-sided LDN is preventable, if the ureter and GV are ligated or clipped above the level of iliac vessels bifurcation.
