“…In the study group, the intra-operative distal ureteric diameter (median [range] 6 [5][6][7][8][9][10][11][12] mm) was significantly smaller than the distal ureteric diameter on preoperative ultrasonography (median [range]15 [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] mm; P = 0.004). Regarding ureteroplasty, ureteric plication was performed only in case 5 because the intra-operative distal ureteric diameter was 12 mm, and the ureteric stent was retained.…”

Objective To determine the long‐term safety and efficacy of ureteric reimplantation with psoas bladder hitch (PBH) in patients aged <12 months with unilateral obstructive megaureter (OM). Patients and Methods We retrospectively compared a group of patients aged <12 months (study group) with an group of patients aged ≥12 months (comparison group), who underwent PBH for OM between September 2007 and April 2017, in terms of preoperative patient characteristics, intra‐ and peri‐operative results, and postoperative results. Results The study group comprised seven infants, five boys and two girls. The median (range) age at the time of PBH was 3 (2–8) months; OM was detected by ultrasonography during the fetal period. The left side was affected in four infants and the right side in three. Four infants had primary OM (POM). In all three infants who had ectopic OM in the complete double renal pelvis and ureter, the OM involved the ureter from the upper half of the kidney. The median (range) follow‐up period after PBH was 45 (33–129) months. Comparison of the two groups showed no significant difference in terms of surgical time (P = 0.948) and length of hospital stay (P = 0.125). In both groups, hydroureteronephrosis improved postoperatively in all patients. There was no significant difference between the two groups in terms of postoperative complications, such as vesico‐ureteric reflux, febrile urinary tract infection and deterioration of ipsilateral renal function. Notably, no patient underwent reoperation in either group. Conclusion Psoas bladder hitch for unilateral OM including POM appears to be safe and effective in the long term for patients aged <12 months and for those aged ≥12 months. Although not routinely recommended, PBH appears to be a viable option for selected infants with POM.

“…19,20 Temporary Double-J stent placement is also accompanied by several complications, including stent migration, encrustation, UTI, and stone formation. 18 Bladder dysfunction is another complication of open surgery in this age group. 14,29 The need for intervention for the aforementioned group and the remarkable complications of the open surgical techniques have led to emergence of minimally invasive methods that preserve renal function with acceptable postoperative results and minimal postoperative complications.…”

Introduction: The study aimed to evaluate the advantages of temporary inguinal ureterostomy in the management of neonates with uropathies and early or recurrent pyelonephritis. Patients and Methods: We performed a retrospective analysis of all patients who underwent ureterostomies between 1989 and 2012, with specific regards to indications and outcomes. We also performed a survey of parents to evaluate their acceptance of diversion. Results: We included 18 patients (12 primary high-grade vesicoureteral reflux [VUR] and 6 primary obstructive megaureters [MUs]). Indications were recurrent febrile urinary tract infections (UTIs) despite antibiotic prophylaxis, doubtful function of the overlying kidney for the oldest cases, when renal function was only assessed by intravenous urography, or both. Cutaneous diversion was performed between the ages of 2 weeks to 5 months (median: 1.8 months). Renal function was assessed prior to undiversion to choose between reimplantation and nephrectomy. The incidence of febrile UTIs significantly decreased during the period of diversion. Urinary diversion was judged socially acceptable by parents. Ureterostomy did not modify the overlying kidney function. Conclusion: Temporary inguinal ureterostomy does not enable better evaluation of renal function by suppressing the pressure of an obstacle or refluxing urines. Its remaining indication seems to be the prevention of recurrent UTIs in neonates and infants with VUR or MU, pending reimplantation.
