[Ureteropyeloscopy and contact ureterolithotripsy in pregnancy]

We conducted 8200 transurethral ureteropyeloscopies (UPS) including transurethral contact ureterolithotripsies (CULT) in pregnant women using semirigid ureteroscopes, pneumatic lithotriptors. Basing on the experience gained we performed 66 UPS and CULT in pregnant women with suspected symptomatic ureterolithiasis: 16 (24.2% in trimester I, 32 (48.4% 0 in trimester II, 18 (27.3%)--in trimester III. Ureteral stones were detected in 37 patients. Interventions were performed without accompanying x-ray examination. Fragmentation of the stones was made in 34 cases. In 3 cases the stone migrated into renal cavity. No stones were found in 27 cases. Stent was not inserted after fragmentation in ureterolith location in the lower third of the ureter. Complications in pregnancy in early postoperative period were not seen. UPS and CULT were highly informative, effective and safe methods of examination and treatment of pregnant patients with suspected symptomatic ureterolithiasis.
