This study aimed to evaluate the effectiveness of probiotics (Lactobacillus rhamnosus GG), as a preventive measure of antibiotic-associated diarrhea (AAD) in children who underwent hypospadias repair and its clinical consequences on postoperative outcome, comparing the group treated with probiotics + antibiotics with two control groups (only antibiotics and antibiotics + placebo). We performed a prospective, randomized, placebo-controlled study with three groups of patients (30 boys for each group) who underwent hypospadias repair in our unit from March 2016 to December 2016. G1 received antibiotics + probiotics (L. rhamnosus GG), while G2 and G3 respectively received only antibiotics or antibiotics + placebo (glucose solution at 5%) for the same period. The patients were evaluated in regard to the number of evacuations/day, stool consistency, and the number of dressings/day. The overall incidence of postoperative AAD was 33.3% (30/90), and it was statistically lower in G1 patients compared to G2 and G3 ones (p = 0.002). The duration of AAD was significantly longer in G2 and G3 compared to G1 (p = 0.001). In G1, the frequency of dressing change was significantly lower compared to G2 and G3 (p = 0.001).The incidence of postoperative complications (fistula and dehiscence) was significantly higher in G2 and G3 compared to G1 (p = 0.001). Our study confirmed that the use of probiotic L. rhamnosus GG associated with antibiotics significantly reduced the incidence and the duration of postoperative AAD. In addition, the use of probiotics LGG reduced the frequency of dressing changes and the incidence of postoperative complications, such as urethral fistula and foreskin dehiscence.
