A comparison of preoperative and postoperative testicular volume and blood flow in patients with inguinal hernia, hydrocele, and cord cyst: A prospective cohort study

Abstract

Objective:To evaluate the effect of inguinal operations performed with a modified Ferguson technique upon testicular volume and blood flow.Methods:This study involved 23 children receiving surgery for inguinal hernia, hydrocele, and cord cyst. This was a prospective study performed between April 2016 and June 2016 in a medical faculty pediatric surgery unit. The color Doppler ultrasound (CDUS) was used to assess testicular volume and blood flow before and after a modified Ferguson technique surgery. The pre- and post operative testicular volume and blood flow were compared with the contralateral testes. SPSS software was used to statistically analyze the data arising; the Mann-Whitney U test and Friedman test were used to compare samples, and P<0.05 was accepted as statistically significant.Results:Preoperative and postoperative testicular volumes were not statistically different when compared to contralateral testes. In patients with right sided inguinal pathology, testicular blood flow on the right side was significantly lower than that on the left side (P=0.023). The testicular blood flow was not statistically different compared with the contralateral testes during the first week evaluation and first month evaluation. The blood flow, probably reduced due to the pressure caused by inguinal pathology, was normalized through surgery.Conclusions:The modified Ferguson technique do not change the testes volume and blood flow.

Analysis of volume change of the testis after inguinal hernia repair using the PIRS method – a prospective pilot study

“…When preoperative, early postoperative, and late postoperative testicular volumes and blood flow of the testes with a pathological condition were compared using the Friedman test, there was no statistically significant difference in testicular blood flow (p > 0.05 in all groups). A slight increase in testicular blood flow in the pathological testes during the early postoperative period returned to normal during subsequent postoperative measurements; however, this difference was not statistically significant [22].…”

Comparison of Preoperative and Postoperative Testicular Elasticity and Vascularity in Pediatric Patients With Inguinal Hernia

“…However, other studies have shown that Doppler parameters are not affected in the early postoperative period. Importantly, measurement of RI may not always be effective in prepubertal children because testicular flow is not robust 19 …”

Prospective ultrasonographic study of blood flow and testicular volume in patients submitted to surgical repair of inguinal hernia without using prosthesis

“…Tuncer et al 16 studied the testicular arterial flow and volume after intervention on the inguinal region without the use of a mesh in 23 children and reported that patients with inguinal hernia, cord cysts and hydrocele on the right presented a decrease in the preoperative period of the testicular arterial flow with statistical significance, but this alteration was reversed after surgery. They attributed the decreased flow to the compression of the vessels of the spermatic cord, but did not explain why this alteration did not occur to the left.…”
