Treatment of paediatric urolithiasis by extracorporeal shock-wave lithotripsy.
1988
Non-surgical removal of renal and ureteral stones has proven successful in adults. In this study, 21 paediatric patients have been treated with the first generation extracorporeal shock-wave lithotriptor and an additional 13 children with a second generation local shock-wave lithotriptor. A total of 47 stones was treated. Treatment-related complications such as colics (17%/18.8%) or fever (8.3%/6.2%) were minimal. Stone passage occurred in 93% and 100%, respectively of each group. Open surgery is still the treatment of choice for large staghorn calculi. Extracorporeal shock-wave lithotripsy can be performed successfully in paediatric nephrolithiasis with stones of limited size.
Ultrasound litholapaxy of a staghorn calculus.
1977
Abstract A method for removal of a staghorn calculus from the kidney through 1 channel of a U-tube nephrostomy is presented. An ultrasound lithotriptor provided a safe and quick alternative to surgical treatment
Imaging modalities and treatment of paediatric upper tract urolithiasis: A systematic review and update on behalf of the EAU urolithiasis guidelines …
2020
Prompt diagnosis and treatment of paediatric urolithiasis are required to avoid long term sequelae of renal damage.To systematically review the literature regarding the diagnostic imaging modalities and treatment approaches for paediatric urolithiasis.PubMed, Science Direct, Scopus and Web of Science were systematically searched from January 1980-January 2019. 76 full-text articles were included.Ultrasound and Kidney-Ureter-Bladder radiography are the baseline diagnostic examinations. Non-contrast Computed Tomography (CT) is the second line choice with high sensitivity (97-100%) and specificity (96-100%). Magnetic Resonance Urography accounts only for 2% of pediatric stone imaging studies. …
Extracorporeal shock wave lithotripsy with ultrasound-guided lithostar plus.
1992
Abstract Since 1989, the Siemens lithostar plus, an upgrade of the lithostar with the ultrasonically guided overhead module, has been available for clinical use. This unit may be used for the treatment of either biliary or urinary calculi. We report on 75 patients with urinary calculi treated between March 1989 and June 1990 with the lithostar overhead module. Stone localization showed a rate of: caliceal stones 33.5%, pelvic stones 44%, upper ureteral stones 9.3% and lower ureter stones 13%. The overall disintegration rate was 86%, with a stone-free rate after 3 months of 78%.
Gas-containing renal stones: a red flag for renal infection.
2022
Background Gas in the renal excretory system is described as a consequence of recent procedures but it can be a sign of severe conditions such as fistulas or infections; however, gas-containing renal stones are only rarely encountered. Purpose To describe the association of gas-containing renal stones and urinary tract infection. Material and Methods We performed a retrospective evaluation of the clinical and imaging findings in a series of six patients with gas-containing renal stones and compared our findings with those of patients with gas-containing renal stones reported in the literature. Urine and stone cultures were used as a diagnostic standard for urinary tract infection. Results I…
Future perspectives of flexible ureteroscopy
2019
Purpose of review In the recent past, there were numerous and promising technological developments in the field of endourology leading to tremendous changes in the management of urolithiasis. This review will try to weave ancient stone therapy with the very modern advent of flexible ureteroscopy and recent developments in robotic systems. Recent findings In the broad field of flexible ureteroscopy for stone surgery, new disposable scopes have been developed and established. The use of robotic instruments is also a new and interesting concept. Additionally, clinical research on the understanding of laser features leads to a specific and appropriate use of lasers for lithotripsy, both holmium…
