RESUMO
ObjectiveTo explore the efficacy and indications of three kinds minimally invasive surgery treatment of upper ureteral calculus (UUC) complicating hydronephrosis.MethodsFour hundred and ninety-two patients with UUC complicating hydronephrosis were divided into three groups:minimally percutaneous nephrolithotomy (mPCNL) group (310 patients),ureteroscopy lithotripsy(URSL) group ( 130 patients) and retroperitoneal laparoscopic ureterolithotomy (RLU) group (52 patients).The operation time,blood loss,length of stay,stone-free rate and postoperative complications in three groups were compared.ResultsThe stone-free rate was 91.0％(282/310) in mPCNL group,78.5％(102/130) in URSL group and 100.0％(52/52) in RLU group,mPCNL group and RLU group were significantly higher than URSL group (P ＜0.01 ).URSL group and RLU group had the advantage of less operation time,blood loss,length of stay and postoperative complications compared with mPCNL group [ RLU group:(55.8 ± 20.5 ) min,( 10.8 ± 3.2)ml,(6.3 ± 2.1 ) d,1.9％(1/52) ;URSL group:(56.5 ± 15.2) min,(8.6 ± 1.4) ml,(5.7 ± 1.6) d,1.5％(2/130);mPCNL group:(113.8 ±42.5) min,(132.8 ±40.2) ml,(12.5 ±2.4) d,8.4％(26/310),P＜ 0.01 ].Conclusions Minimally invasive surgery on the treatment of UUC is safe and effective.URSL is preferred to treating the small UUC,RLU can improve the success rate for larger UUC.Contrary to mPCNL,which is best for merger kidney calculus,has higher stone-free rate,can be used as supplement of URSL after treatment failure.
RESUMO
Objective To investigate the effect of repeat transurethral resection for superficial bladder cancer. Methods One hundred and twenty patients who were newly diagnosed superficial bladder cancer were divided randomly in to two groups by mechanical sampling method,60 patients underwent second of prostate TUPKVP 4 weeks after initial transurethral and received adjuvant MMC intravesically (experiment group) and the other 60 patients received adjuvant MMC following the initial TUPKVP(control group). The two groups were followed up by cystoscopy at 3-month intervals,and then compared the recurrences between the two groups. Carcinoma in situ or muscle invasive disease were excluded from the study. Results Mean following up time was 6-24 (12.0 ±6.5) months, within the following up period,recurrence was observed in 13 (21.7%, 13/60) patients in experiment group and in 38 (63.3%,38/60)patients in control group, there was signiticantly statistical difference between the two groups (P＜ 0.01). Of all the recurrences, the recurrence rate of high grade tumor was 26.2% (11/42) in experiment group and 70.0% (35/50) in control group,the recurrence rate in experiment group was obviously less than that in control group (P ＜ 0.01). Conclusions Repeat transurethral resection can lower the recurrence of superficial bladder cancer (especially for the high grade tumor) which with initial resection, it can improve the classification of malignant rumor, and find the residual tumor, so it has value in clinical treatment.
