Abstract

For over 35 years shock wave lithotripsy has proven to be an effective, safe and truly minimally invasive option for the treatment of nephrolithiasis. Various technical factors as well as patient selection can impact the success of the procedure. We used published work focusing on outcomes of shock wave lithotripsy, risk of complications, and strategies for improving stone fragmentation to create this review. Multiple patient and technical factors have been found to impact success of treatment. Skin to stone distance, stone density and composition, size and location of the stone within the urinary system all influence stone free rates. A slower rate with a gradual increasing voltage, precise targeting, proper coupling will improve stone fragmentation and decrease risk of complications. The selection of appropriate patients through a shared decision making process and attention to the technical factors that improve stone free rates is key to providing an effective treatment and patient satisfaction.

Abstract

Purpose: This study presents a comparison of the international experience with ipsilateral and bilateral ureteroscopy for multiple, bilateral ureteral and renal stones vs single stone treatment. Patient and treatment characteristics and outcomes were compared. Materials and Methods: The CROES (Clinical Research Office of the Endourological Society) Ureteroscopy Global Study includes 114 centers in 32 countries. Patients undergoing bilateral ureteroscopy, ipsilateral ureteroscopy for multiple stones and ureteroscopy for a single stone were examined from January 2010 to October 2012. Intraoperative characteristics and postoperative outcomes were identified for each patient. Inverse probability weighted regression adjustment analyses were done to compare outcomes independent of differences among centers and patient characteristics. Results: The CROES Ureteroscopy Global Study consists of 11,885 patients. A total of 2,153 patients (18.7%) were treated for multiple stones, of whom 1,880 (87.3%) and 273 (12.7%) underwent ipsilateral and bilateral ureteroscopy, respectively. Inverse probability weighted regression adjustment models for bilateral vs ipsilateral ureteroscopy and multiple vs single stone treatments showed that patients with bilateral ureteroscopy and multiple stone treatments had lower stone-free rates, higher re-treatment rates and longer operative times compared to patients who underwent ipsilateral ureteroscopy and single stone treatment. There was no difference in complication rates among bilateral, ipsilateral and single stone ureteroscopy. Conclusions: This study presents a large series of patients who underwent bilateral and ipsilateral ureteroscopy. Our findings suggest a decrease in stone-free rates, increased re-treatment rates, increased operative times and longer hospital stay in patients treated for multiple stones. The treatment of multiple stones and bilateral ureteroscopy are safe compared to single stone treatment and ipsilateral ureteroscopy, respectively., Boston Scientific
