Introduction. The active introduction of lasers in practical urology has become a strong factor in the development of minimally invasive surgery in the treatment of ureterolithiasis. Currently, laser contact ureterolithotripsy is one of the most effective ways to treat patients with ureteral stones, especially pregnant women. The search for new methods of treatment, including transurethral, for urolithiasis is of great practical importance. The paper presents the results of contact lithotripsy of ureteral stones in pregnant women. Objective. To study the possibility of using laser lithotripsy of ureteric stones in pregnant women with urolithiasis and its results. Material and methods. Retrograde contact ureterolithotripsy was performed in 10 pregnant women with urolithiasis between 16 and 28 weeks’ gestation. The indications for this operation were established each time individually together with the obstetrician and anesthesiologist. All operations were performed only under visual and ultrasound control using a semi-rigid ureteropyeloscope with a distal part size of 8 Ch and a laser device without the use of Rx control. Results. In all cases, crushing and complete removal of ureteral stones was possible. There were no complications associated with the ureteropyeloscope and contact crushing of the stone. The operation ended with the installation of a stent JJ ureteral for 10 days. All patients were followed until delivery. All women were able to achieve long-term uroculture sterility. Conclusion. The use of retrograde contact ureterolithotripsy in the second trimester of pregnancy is a reasonable, minimally invasive surgical method for the treatment of urolithiasis, which avoids long-term stenting of the ureter or the installation of a nephrostomy.
