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

Introduction: Laparoscopic surgery of inguinal hernias in children using the PIRS method is a recognized method of treat- ment that has been used for several years. Aim of the research: To assess the effects of inguinal hernia repair performed with the percutaneous inguinal ring suturing (PIRS) method on the volume of the testicles. Material and methods: It was a prospective study conducted between January 2016 and December 2019 in the Department of Paediatric Surgery. Twenty-nine male patients aged 0–8 years were included in the study. Ultrasound evaluation of both testicles, comparing the volume before and after inguinal hernia repair, was performed. Results and conclusions: The ultrasound measurements of the testicular volume after the surgical procedure showed no inhibition of growth with the preoperative sonographic examination and concerning the testis of the opposite, non-operated side. The increase in the median of the volume of both testis’ was observed in cases before and after the elective surgeries, although there was no statistically significant difference. Emergency operation due to the incarcerated hernia on either side did not statistically significantly affect testicular volume in the tested group of patients. None of the laparoscopically operated patients showed atrophy of the testis. Laparoscopic surgery using the PIRS method in the case of inguinal hernia does not result in testicular atrophy or a decrease of the volume of the testis on the operated side.
