Comparison of the Efficacy of Transurethral Holmium Laser and Electric Incision in the Treatment of Cystitis Glandularis:Randomized Controlled Trial / 中国微创外科杂志

ABSTRACT

Objective To compare the clinical efficacy of two minimal invasive surgeries,transurethral Holmium laser and electric incision,in the treatment of cystitis glandularis(CG).Methods From January 2004 to June 2006,63 cases of CG were confirmed pathologically by using cystoscopy.Among the patients,35 were treated by transurethral Holmium laser and 28 by transurethral electric incision.All the cases received postoperative chemotherapy with mitomycin bladder irrigation and were followed up for 6 to 18 months.The efficacy of the two surgical procedures was evaluated during the follow-up.Results Compared with the electric incision group,the mean operation time and hospital stay was significantly shorter [(15.3?5.1) min vs(20.8?6.3) min,t=-3.831,P=0.000;and(2.4?1.7) d vs(4.0?1.5) d,t=-3.909,P=0.000;respectively],and the rate of complications was significantly lower [0%(0/35) vs 14.3%(4/28),?2=5.339,P=0.021] in the Holmium laser group.Six months after the operation,the cure rate of the Holmium laser group was significantly higher and the recurrence rate was significantly lower than those in the electric incision group [82.9%(29/35) vs 60.7%(17/28),?2=3.871,P=0.049;and 5.7%(2/35) vs 25.0%(7/28),?2=4.725,P=0.030].Conclusions The transurethral Holmium laser is a safe,effective,and convenient method for the treatment of CG.Since the method can not only achieve a high cure rate and low recurrence rate,but also avoid lower urinary obstruction,we recommend it as the first choice for CG.
