Abstract:
Objective To determine the efficacy and long-term outcome of pyeloureteroplasty in the ureteropelvic junction obstruction (UPJO) patients with poor kidney function(＜ 10％).Methods The data of UPJO patients with poor kidney function treated from January 2006 to September 2016,was retrospectively analyzed.The renal function ＜ 10％ undergoing pyeloureteroplasty were included.Ipsilateral vesicoureteric reflux,ureterovesical junction obstruction and renal dysplasia were excluded.39 patients was enrolled.There were 31 boys and 8 girls.The mean age at surgery was 3.1 years old (range 7 months-14 years).There were 36 primary UPJO and 3 extrinsic vessel cases.Twenty-seven cases of UPJO in left side,9 cases in right side,and 1 case in bilateral side.The preoperative examination included ultrasound,intravenous pyelography (IVU) and 99 mTc DTPA renography.Mean anteroposterior diameter of pelvis was (5.5 ± 2.4) cm before operation (range 3.4-7.4cm);IVU showed non visualized kidney or rim sign.The ill kidneys' mean renal function was (3.25 ± 2.78) ％ (range 0-9％).Results Open pyeloureteroplasty were performed in the 38 patients,additional nephrectomy was required in 1 because of repeated urinary infection,while the other patients had good prognosis,nephrostomy was kept until 2-3 days' successful clipping.Laparoscope pyeloplasty were performed in one patient with double-J.The patient had urinary infection post operation and was cured.The postoperative examination included ultrasound,intravenous pyelography and 99mTc DTPA renography were performed after 3-6 months.Mean anteroposterior diameter of pelvis was (3.2 ± 1.9) cm (range 2.1-4.5 cm);Intravenous urography showed visualized kidney;Mean renal function was (18.16 ± 13.17)％ (9％-27％).There was significant difference between preoperational and postoperational evaluation of renography and pelvis (P ＜ 0.05).There was no correlation between the changed renal function and age (P ＞ 0.05).The mean follow-up time was 10.2 months (range 6-25 months).Conclusions Pyeloureteroplasty could be safe and feasible for the UPJO patients with renal function less than 10％,and could improve the renal function.
