Abstract:
Objective To investigate the influence of laparoscopic D3 lymphadenectomy combined with pelvic autonomic nerve preservation on the urinary function of male patients with rectal cancer. Methods From August 2006 to August 2007, 119 male patients with rectal cancer who had been admitted to Southwest Hospital were assigned to open surgery group (n=59) and laparoscopic group (n=60) according to the random number table. Three months after the operation, the urinary function of patients was assessed by urodynamics investigation and international prostate symptom score (IPSS). Differences in measurement data were compared with paired t test. Results There was no significant difference in IPSS between laparoscopic group (10.9±2.9) and open surgery group (11.5±3.1) (t=-1. 309, P>0.05). The maximum flow rate, voided volume, residual urine volume, detrusor contraction pressure and maximum urethral pressure were 15.2 ml/s, 150.1 ml, 6.1 ml, 43.3 cm H2O (1 cm H2O=0.098 kPa) and 77.5 cm H2O in laparoscopic group, and 15.0 ml/s, 140.9 ml, 6.4 ml, 45.6 cm H2O and 72.3 cm H2O in open surgery group, with no statistical difference between the 2 groups (t=1.22, -2.12, -1.73, -1.35, -1.64, P>0.05). Conclusions Laparosceopic D3 lymphadenectomy combined with pelvic autonomic nerve preservation is relatively safe in preserving urinary function, and its efficacy is comparable to that of open surgery.
