Is Ureteroscopy beneficial in pregnant females with symptomatic urolithiasis? Study sheds light

CHINA: According to a recent study published in BMC Urology, ureteroscopy and internal ureteral stents have little to no effect on fertility outcomes when used to treat pregnant patients with symptomatic urolithiasis, and when circumstances allow, URS may be more beneficial for pregnant patients with urinary stones.

It has been estimated that between 1 in 2000 and 1 in 200 pregnant women have symptomatic urinary tract stones. The most common therapies for pregnant women with symptomatic urolithiasis include ureteroscopy (URS) and internal ureteral stents. The placement of a double-J (D-J) stent is a temporary measure, and there are few studies on this procedure, until definitive treatment during the postpartum period. URS has emerged as the standard of care for the treatment of ureteric stones in pregnancy as a result of ongoing improvements in endoscopic technology and endourological procedures.

The researchers aimed to compare the effectiveness of ureteroscopy (URS) against internal ureteral stents in treating urolithiasis in pregnant women.

For this objective, through meticulous literature searches, pertinent studies released between January 1980 and June 2022 were found. In the beginning, 499 studies were found. They included pregnant women of any gestational stage who underwent double-J (D-J) stent implantation alone or ureteroscopy for the treatment of urolithiasis; a study was considered included if it had more than 10 participants. Finally, a total of 25 studies were identified, with 789 individuals undergoing URS and 131 cases undergoing serial stenting.
