Abstract

fetched live from OpenAlex

INTRODUCTION: There is little documentation of the efficacy of the Doli-S lithotripter. This study investigated the outcome of ESWL with the Doli-S lithotripter on previously untreated renal calculi. METHODS: Over a 12 month period, 105 consecutive patients with renal stones, treated by a single urologist were enrolled in the study. None of the stones were previously treated. Data gathered included stone characteristics and treatment characteristics. Treatment was to an endpoint of either fluoroscopically successful fragmentation or to 2500 shockwaves. Patients were followed with KUBs, ultrasounds, or CT-KUBs to assess residual stone burden. Treatment success was defined as complete clearing of the calculus, or residual fragments of less than 3 mm. RESULTS: One hundred five patients were treated and 16 were lost to follow-up. One hundred nineteen stones in 89 patients were included in our analysis. Mean follow-up was 115 days. The average stone size (expressed as mean of two measured stone dimensions) was 7.8 mm. After a single lithotripsy treatment, the overall treatment success rate was 47.9%. The left kidney accounted for 58% of the treated stones. Treatment success was greater for left renal stones than right-sided stones (55.1% versus 38.0%, p = 0.033). There was no significant difference in treatment success rates for calyceal location of stones. Lower pole stones were treated successfully in 57.9% of cases. Smaller stones (3 mm-10 mm) were more successfully treated than larger stones (10 mm-20 mm) (55.6% versus 24.1%, p = < 0.001). CONCLUSIONS: Success rates for the Doli-S lithotripter for a single treatment of previously untreated renal stones ranged from 24%-58%, depending on stone size and location. These rates are lower than success rates reported for other lithotripters. Inferior pole calculi had a higher treatment success rate than previously reported. Factors associated with treatment success included smaller stone size, left-sided stones, and ease of fluoroscopic visualization.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
