Purpose: Urinary calculi is a familiar disease. A well-known complication of endourological treatment for impacted ureteral stonesis the formation of ureteral strictures, which has been reported to occur in 14.2% to 24% of cases. Materials and Methods: This was a prospective study. Ureterotripsy treatment was used on patients with impacted ureteralstones. Then, after 3 months and 6 months, the condition of these patients was assessed by means of a kidney-ureter-bladder (KUB)ultrasound. If the KUB ultrasound indicated moderate to serious hydronephrosis, the patient was further assessed by means of acomputed tomography intravenous urogram or retrograde pyelogram to confirm the occurrence of ureteral strictures. Results: Of the 77 patients who participated in the study, 5 developed ureteral strictures. Thus, the stricture rate was 7.8%. Ananalysis of the intraoperative risk factors including perforation of the ureter, damage to the mucous membrane, and residual stoneimpacted within the ureter mucosa revealed that none of these factors contributed significantly to the formation of the uretericstrictures. The stone-related risk factors that were taken into consideration were stone size, stone impaction site, and duration ofimpaction. These stone factors also did not contribute significantly to the formation of the ureteral strictures. Conclusions: This prospective study failed to identify any predictable factors for ureteral stricture formation. It is proposed that allpatients undergo a simple postoperative KUB ultrasound screening 3 months after undergoing endoscopic treatment for impactedureteral stones.

Haematuria is a common presentation of bladder cancer and requires a full urologic evaluation. This study aimed to develop a scoring system capable of stratifying patients with haematuria into high or low risk groups for having bladder cancer to help clinicians decide which patients need more urgent assessment. This cross-sectional study included all adult patients referred for haematuria and subsequently undergoing full urological evaluation in the years 2001 to 2011. Risk factors with strong association with bladder cancer in the study population were used to design the scoring system. Accuracy was determined by the area under the receiver operating characteristic (ROC) curve. A total of 325 patients with haematuria were included, out of which 70 (21.5%) were diagnosed to have bladder cancer. Significant risk factors associated with bladder cancer were male gender, a history of cigarette smoking and the presence of gross haematuria. A scoring system using 4 clinical parameters as variables was created. The scores ranged between 6 to 14, and a score of 10 and above indicated high risk for having bladder cancer. It was found to have good accuracy with an area under the ROC curve of 80.4%, while the sensitivity and specificity were 90.0% and 55.7%, respectively. The scoring system designed in this study has the potential to help clinicians stratify patients who present with haematuria into high or low r isk for having bladder cancer. This will enable high-risk patients to undergo urologic assessment earlier.
