title: Which treatment method should be used in pregnant patients with ureteral calculi? Two center comparative study.
abstract: OBJECTIVE
  We aimed to compare ureterolithotripsy and inserting only ureteral-j stent in terms of efficiency, safety and patient comfort in treatment of ureteral calculi in pregnant patients.
  
  
  METHODS
  Seventy patients who developed hydronephrosis due to ureteral calculi during pregnancy, and on whom endoscopic intervention was performed were included in the study. In a center, the stones were broken up by ureteroscopy, and then ureteral stents (JJ) were placed if needed. In the other center, nothing was performed on the stones, and only ureteral stents (JJ) was placed. For the statistical analysis, Pearson's chi squared test and the Mann-Whitney U tests were used and the significance level was determined as p < 0.05.
  
  
  RESULTS
  The average age of the patients was 26.2 years (18-39) and the average gestational week was 23.4 weeks (8-36). While no significant difference was found between the two groups in terms of the frequency of complications (p=0.381) and post-operative pyelonephritis (p=0.2), the need for additional intervention in the group on whom ureteroscopy was performed was found to be less (9.7% vs. 31%; p=0.032). Moderate or severe LUTS or flank pain during the period between the procedure and the birth was found to be significantly less in the group in which ureterolithotripsy was performed (14% vs. 55%; p=0.036).
  
  
  CONCLUSIONS
  Ureterolithotripsy is a safe and more comfortable procedure than only ureteral double-j insertion on pregnant patients with ureterolithiasis.
