“…Abou Heidar et al . 10 developed a nomogram to predict the factors of spontaneous stone passage failure and concluded that female gender, high creatinine level, elevated neutrophil-to-lymphocyte ratio, stone size greater than 5 mm, proximal stone, hydronephrosis, and leukocyte esterase greater than 75 significantly decreased spontaneous stone passage. The medical treatment is usually to reduce edema and spasms and promote smooth muscle relaxation to facilitate stone expulsion 3 , 9 .…”

Background: The role of sexual intercourse as an alternative treatment approach for ureteral stones is a recent area of investigation with only small sample-sized studies. This study aims to evaluate the role of sexual intercourse in the spontaneous passage of distal or intramural ureteral stones via a larger sample size. Materials and Methods: The study population included cases that had either a distal ureteric or an intramural radiopaque stone. The patients were divided into two groups; Group A was instructed to engage in sexual intercourse 2-3 times per week while also receiving symptomatic treatment for 4 weeks. Group B received symptomatic treatment alone and was instructed to abstain from sexual intercourse or masturbation for the same period. Results: A total of 160 male patients were enrolled in this study. The ages of the patients ranged from 21 to 58 years. The rate of stone expulsion after two weeks was 68.18% in Group A and 53% in Group B (P-value=0.053). The expulsion rate after 4 weeks was 80% in Group A and 68.4% in Group B (P-value=0.072). The mean expulsion time was 13.9±5.4 days for the experimental group and 15.2±6.7 days for the control group (P-value=0.179). The experimental group required fewer analgesic injections in comparison to the control group (P-value <0.05). Conclusion: While the role of sexual intercourse in facilitating the passage of distal or intramural ureteral stones cannot be fully established, it may aid to some extent. However, it should not be relied upon as a standalone treatment modality.

Introduction: Recent studies have shown that software-generated 3D stone volume calculations are better predictors of stone burden than measured maximal axial stone diameter. However, no studies have assessed the role of formula estimated stone volume, a more practical and cheaper alternative to software calculations, to predict spontaneous stone passage (SSP). Methods: We retrospectively included patients discharged from our emergency department on conservative treatment for ureteral stone (≤10 mm). We collected patient demographics, comorbidities, and laboratory tests. Using non-contrast computed tomography (CT) reports, stone width, length, and depth (w, l, d, respectively) were used to estimate stone volumes using the ellipsoid formula: V=π*l*w*d*0.167. Using a backward conditional regression, two models were developed incorporating either estimated stone volume or maximal axial stone diameter. A receiver operator characteristic (ROC) curve was constructed and the area under the curve (AUC) was computed and compared to the other model. Results: We included 450 patients; 243 patients (54%) had SSP and 207 patients (46%) failed SSP. The median calculated stone volume was significantly smaller among patients with SSP: 25 (14–60) mm3 vs. 113 (66–180) mm3 (p<0.001). After adjusting for covariates, predictors of retained stone included: neutrophil to lymphocyte ratio (NLR) ≥3.14 (odds ratio [OR] 6, 95 % confidence interval [CI] 3.49–10.33), leukocyte esterase (LE) >75 (OR 4.83, 95% CI 2.12–11.00), and proximal stone (OR 2.11, 95% CI 1.16–3.83). For every 1 mm3 increase in stone volume, the risk of SSP failure increased by 2.5%. The model explained 89.4% (0.864–0.923) of the variability in the outcome. This model was superior to the model including maximal axial diameter (0.881, 0.847–0.909, p=0.04). Conclusions: We present a nomogram incorporating stone volume to better predict SSP. Stone volume estimated using an ellipsoid formula can predict SSP better than maximal axial diameter.
