ABSTRACT
Objective To investigate the clinical efficacy of the urethra URSL combined with micro-puncture and drainage treatment for pediatric calculus of lower urinary tract. Methods From January 2003 to January 2013, 66 cases with pediatric urinary tract calculi in our hospital were randomly equally divided into experimental group and control group. The experimental group was treated with transurethral bladder micro URSL combined puncture and drainage treatment, and the control group was given a simple transurethral URSL method of treatment. The operative time, postoperative urine turned clear time,pulling stone clearance after catheter time,postoperative hospital stay and the incidence of postoperative urethral stricture were observed and recorded. In addition, these data were compared between the two groups. Results The operations of two groups have successfully completed. The mean operative time, postoperative urine turned clear time, pull out the catheter stone clearance after time and postoperative hospital stay of control group was 30.2±2.45 minutes,2.5±0.5 days,2.1±0.8 days and 4.0±0. 5 days, respectively. Patients were followed up 1 year after operation, and 1 case of urethral stricture occurred. However, the mean operative time, postoperative urine turned clear time, pull out the catheter stone clearance after time and postoperative hospital stay of the test group was 20.36±2.35 minutes,1.5±0.7 days,1.1±0.25 days and 3.1±0.3 days,respectively,with no urethral stricture case occurred. There were significant differences between the two groups ( <0.05) . Conclusion Transurethral bladder URSL micro puncture and drainage combined with transurethral ureteroscopy lithotripsy treatment for children with lower urinary tract calculi has better efficacy and safety. It could shorter operative time, postoperative urine turned clear time, the gravel discharge time and average hospitalization time, reduce the incidence of postoperative secondary urethral stricture.
ABSTRACT
Objective To investigate the feasibility and safety of endoscopic treatment of ureteral calculi acute obstruction with urinary extravasation. Methods 56 patients with ureteral calculi acute obstruction and urinary extravasation were randomly divided into two groups:the treatment group and the control group,28 cases in each group. Patients in the treatment group were given URSL or percutaneous nephrostomy drainage, and the secondary fistula was given URSL stone clearance treatment. Patients in control group were given traditional ureterolithotomy treatment. The stone clearance rate, the average recovery time after surgery, postoperative wound infection rate and the abnormal rate of postoperative albumin were observed in two groups. Results In the treatment group,28 patients had no residual stones with mean postoperative recovery time of (5.2 1.3) days,postoperative fever was found in 3 cases,obvious abnormal postoperative albumin in 3 cases. In the control group,residual stones were found in 3 cases,the average recovery time after surgery was (7.9 2.6) days,postoperative fever was found in 10 cases, and obvious abnormal postoperative albumin in 11 cases. There were statistically significant differences in stone clearance rate, the average recovery time after surgery, postoperative wound infection rate and the abnormal rate of postoperative albumin between two groups (P<0.05) . Conclusion Endoscopic treatment of ureteral calculi acute obstruction and urinary extravasation has advantages including better efficacy, less trauma, less complications and quicker recovery.
