Abstract:
Objective To investigate postoperative urinary function recovery after complete robotic assisted radical cystectomy and in situ U-shaped ileal neobladder.Methods Retrospective analysis of 79 cases of local progression bladder cancer (cT2-3 N0-2 Mo) in our hospital from September 2014 to September 2018.79 cases were confirmed by pathology as high-grade uroepithelium cell carcinoma of bladder.Posterior urethra and bladder neck biopsy did not see tumor invasion.The urodynamic examination for all patients before surgery showed no significant decrease in urinary control function.Preoperative International urinary Incontinence Advisory Committee urinary Incontinence Questionnaire summary confirmed that there was no obvious urinary incontinence symptoms.All patients underwent radical bladder resection and in situ Ushaped ileum new bladder surgery.40 cases in the experimental group were treated with complete robot assisted radical bladder resection and in situ U-shaped ileum new bladder.39 cases in control group were treated with laparoscopic surgery.There was no statistically significant difference between the two groups of general data (both P ＞ 0.05).The operation time,bleeding volume,positive rate of postoperative incision,postoperative hospitalization time,new bladder capacity,residual urine volume,maximum urinary flow rate,bladder internal pressure,unilateral ureteral reflux and stenosis incidence,as well as immediate urinary control rate after extraction of catheter and 1,3,6 and 12 months of urinary control recovery were compared.Results 79 cases of this study were successfully completed.The operation time of the two groups [(286.5 ±37.2) min vs.(288.5 ±32.9) min,P =0.801],intraoperative blood loss[(185.1±41.6) ml vs.(189.3 ±54.2) ml,P =0.700].There was no significant difference in the average postoperative hospital stay [(14.3 ± 1.6)d vs.(14.9 ±2.2)d,P =0.168].The margins of the pathological examinations in both groups were negative.New bladder volume after surgery [(300 ± 10) ml vs.(245 ± 10) ml,P ＜ 0.001].Urodynamic examination of residual urine volume [(20 ± 10) ml vs.(50 ± 10) ml,P ＜0.001],maximum urine flow rate [(16 ±4) m1/s vs.(13 ±2) m1/s,P =0.006].Intravesical pressure [(22.5 ±3.0) cmH2Ovs.(17.5 ± 2.5) cmH2O,P ＜ 0.001] (1 cmH2O =0.098 kPa).The two groups of postoperative cystoscopy showed that unilateral ureteral reflux was 5％ (2/40) and 20.5％ (8/39),respectively,and the unilateral ureteral anastomotic stenosis was 2.5％ (1/40) and 15.4％ (6/39) after operation,and the difference was statistically significant (P =0.038,P =0.044).The urine control rate of the observation group and the control group immediately after removal of the catheter was 37.5％ (15/40) and 15.4％ (6/39),respectively.The urine control rate in 1 month was 62.5％ (25/40) and 38.5％ (15/39),respectively.The urine control rate in 3 month was 82.5％ (33/40)and 56.4％ (22/39),the difference was statistically significant (P =0.026,P =0.033,P =0.012).At other follow up time points,there was no significant difference in point-controlled urine rate (P ＞ 0.05).Conclusions Complete robot-assisted radical cystectomy and in situ U-shaped ileal neobladder surgery are more advantageous than standard laparoscopic surgery in time of the early recovery urinary function.
