Abstract:
Objective To evaluate the efficacy and safety of acute ureteroscopy for the treatment of ureterie stones during middle and late pregnancy.Methods From June 1998 to March 2005,17 pregnant women(mean age,27 years;age range,21-35 years)with ureteric stones were treated by ureteroscopy when the fetus was at 20-36 weeks of gestation(mean,29 weeks).All the cases presented with urgent symptoms such as recurrent renal colic(11 cases),fever(4)or acute obstructive anuria(2).Among 17 cases,the stones(between 6 mm?7 mm and 13 mm?21 mm)were located in the upper(8 cases),middle(5)or lower ureter(4);and on the left side(5 eases),on the right(10)and on both(2)of the lower ureter. Mild hydronephrosis were observed in 6 cases and moderate hydronephrosis in 11,Of the 17 cases,14 under- went ureteroscopic pneumatic lithotripsy;in 1 case the calculi were pushed to the renal pelvis;and 2 cases were treated by Double-J catheter drainage.Results All the urgent symptoms in 17 cases were relieved after treatment.The stone-free rate of initial treatment was 82.4%(14 of 17).Three cases with residual stones were treated by Douhle-J catheters,which were replaced every 3 months until the calculi were re- moved.No abortion,premature delivery or complications such as ureter perforation occurred.Mild renal colic occurred in 1 case after insertion of Douhle-J catheter,and it was relieved 3d later;gross hematuria occurred in l case and disappeared 6 d later without treatment.All 17 patients had normal delivery and gave birth to healthy children.Conclusions Ureteroscopy is a safe and reliable method for the treatment of ureteric calculi during middle and late pregnancy.
