[Experience of 157 vesikoscopic operations in children].

Urologiia; (6): 59-64, 2017 Dec.
Artigo em Russo | MEDLINE | ID: mdl-29376597

AIM:

Recent advances in the field of minimally invasive surgical technologies in children and adolescents have led to the development of vesicoscopic (transvesical, pneumoscopic) access (VA). Current limitations in using VA emphasize the need for further studies investigating surgical options for the management of various pathological conditions of the bladder and ureterovesical junction, the features of surgical techniques and the course of the early postoperative period when used in pediatric urological practice.

MATERIALS AND METHODS:

From 2013 to 2017, 157 patients (79 girls and 78 boys) aged between 2 months and 18 years (mean age 4.9-8.7 years) underwent surgery using VD. Unilateral and bilateral vesicoscopic ureterocystoneoimplantation was performed in 110 (70%) and 44 (28%) patients, respectively. A total of 198 ureters was implanted. Three (1.9%) children underwent vesicoscopic excision of the bladder diverticulum. Transvesicoscopic Cohen ureteric reimplantation, pneumovesical Glenn-Anderson procedure, and Chumakov ureterocystoneoimplantation were performed in 151 (96.1%), 2 (1.3%) and 1 (0.6%) patients, respectively.

RESULTS:

The mean operative time when using VA was 126.8+/-46.7 min. In patients younger than one year, 1-3 years, 4-17 years, it was 136.0+/-43.8 min, 130.1+/-43.5 min and 122.4+/-65.8 min, respectively. The mean length of postoperative hospital stay was 6.2+/-2.3 days. In 3 (1.9%) cases we had to convert to open surgery. Gas migration into the abdominal cavity occurred in 6 (3.8%) patients. Fourteen (9%) patients had early postoperative complications. Transient obstruction of ureterovesical junction occurred in 6 (3.8%) patients. Acute complete obstruction of the distal ureter developed in 3 (1.9%) patients aged three months who did not undergo drainage of the upper urinary tract intraoperatively. A paravesical urine leak occurred in 1 (0.6%) patient. In one (0.6%) of the boys, the distal end of the urinary drainage inserted through the trocar into the ureter migrated in the bladder. The urine leakage from the trocar puncture occurred once (0.6%) and was stopped by indwelling urethral catheterization for seven days. In 2 (1.3%) patients, exacerbation of pyelonephritis required a modification in antibacterial therapy.

DISCUSSION:

Despite the accumulated experience, vesicoscopic surgery remains a laborious and complicated surgical intervention, requiring long learning curves even for surgeons who have good manual skills in laparoscopic surgery.

CONCLUSION:

In our opinion, vesicoscopic access allows the entire range of surgical interventions on the vesicoureteral junction and bladder in children to be performed. It is effective, significantly less traumatic than traditional open cystotomy access, and associated with an excellent cosmetic result.
