[Rehabilitation of patients with "forgotten" stents]

The treatment of patients with large calculi, formed on both ends of the long-standing stent, remains difficult problem of modern urology. We observed 6 patients with long-term (16 to 24 months) standing stents. Large calculi on both ends of the drain were detected in 5 patients, fragmentation of stent--in 1 patient. Indication for stenting was ureteral calculus in 4 patients, staghorn stone of the left kidney in one pregnant woman 26 years old, and the stent was installed during orthotopic cystoplasty in 1 patient. At the first stage, contact laser lithotripsy of calculus on cystic end of the stent was performed, and distal portion was removed with forceps. 2-3 weeks after, PCNL was performed and renal end of the stent was removed. Patient with fragmentation of stent underwent ureteroscopy, and parts of the drainage were removed. To remove the stent, on average 1.8 endourological intervention was required. Results of operations in all cases were successful. Endourological operations are an effective method for the treatment of patients with large calculi, formed at both ends of the "forgotten" stents.
