[Urological symptoms after laparoscopic hernia repair. Reduction with a variant of polypropylene mesh]

In the context of a prospective, randomized, controlled double-blind study concerning a reduction of postoperative, urogenital affections after laparoscopic hernia repair using a polypropylene mesh, laparoscopic polypropylene implantation was performed in 40 male patients. Twenty patients received a heavyweight, rigid polypropylene mesh (group A) and the remainder a heavyweight, but softer polypropylene mesh (group B). Questionnaires were used to assess the severity of pain, impairment of sexual life, appearance of urogenital affections, and general condition. On the 3rd postoperative day, testicle blood circulation and testicle volumes were documented by ultrasound, and a congestion of the plexus pampiniformis was excluded by ultrasound with 5 MHz. Starting in the 1st postoperative week, a prevalence of affections such as testicular sensitivity to touch, pain upon ejaculation, and a pulling sensation during urination became apparent in group A. In the 12th postoperative week, 20% in group A still described testicular sensitivity to touch and 10% pain upon ejaculation and a pulling sensation during urination but only 5% in group B. It is essential to reduce urogenital affections after laparoscopic hernia repair by strict indications and appropriately adapted polypropylene meshes.
