Safety and Efficacy of Combination of Tamsulosin 0.4 mg Plus Tadalafil 5mg Versus 2.5 mg

25 april 2026 bijgewerkt door: Ahmed Amr, Ain Shams University

Safety and Efficacy of Combination of Tamsulosin 0.4 mg Plus Tadalafil 5mg Versus 2.5 mg for Ureteric Stent Related Symptoms

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.

Gedetailleerde beschrijving

Ureteral stents are commonly used for temporary drainage in various urological procedures. Despite their usefulness, they are frequently associated with bothersome symptoms collectively termed as "stent-related symptoms" (SRS),These symptoms include flank pain, lower urinary tract symptoms (LUTS), hematuria, dysuria, urgency, frequency, and sexual dysfunction.

The exact pathophysiology of SRS is multifactorial, involving local irritation, vesicoureteral reflux, and smooth muscle spasm.

Various pharmacological agents have been studied to alleviate these symptoms, with alpha-blockers and PDE-5 inhibitors showing promising results .

Tamsulosin, a selective al-blocker, reduces bladder neck and distal ureteral smooth muscle tone, alleviating irritative urinary symptoms.

Tadalafil, a PDE-5 inhibitor, has been shown to improve LUTS through its smooth muscle relaxation and increased perfusion effects. While both have been studied individually and in combination, the optimal dose of Tadalafil in combination therapy is yet to be clearly established
