Ureteric Stone

Ureteral stenting is a common urological procedure performed to relieve obstruction and facilitate urinary drainage. Despite its effectiveness, stent-related symptoms (SRS) such as dysuria, frequency, urgency, flank pain, and sexual discomfort negatively affect patient quality of life. Pharmacological management with alpha-blockers such as Tamsulosin and phosphodiesterase-5 inhibitors (PDE5i) such as Tadalafil has shown promise in reducing SRS. While low-dose Tadalafil (2.5 mg) has not been explored, its comparative effectiveness against the standard 5 mg dose when combined with Tamsulosin remains under-researched. This study aims to evaluate the difference in reduction of SRS between Tamsulosin with Tadalafil in standard and half dosage.

To compare the efficacy, safety, success rate, operative time, and cost-effectiveness of flexible ureteroscopy versus semirigid ureteroscopy in the management of upper ureteric stones smaller than 2 cm. The investigators' main concern in this study is Upper third ureteric stones to determine which cases can be treated with Semi-Rigid Ureteroscopy, and which one needs flexible ureteroscopy. This depends on several factors: 1. Division of the upper third of the ureter 2. Stone size 3. Stone impaction 4. Surgeon experience 5. Anesthesia 6. Ureteric dilatation above the stone 7. Mini endoscopy

In this study we will test the effect of local intraureteric aminophylline instillation through Ureteric stent and Reaching stone without the need of ballon dilataion
