Filter by:This study will be conducted to compare early (one week) versus delayed (2-4 weeks) definitive ureteroscopic lithotripsy after initial drainage for obstructing ureteral or renal stones associated with infection.
In this study, we will see the feasibility of a non-opioid pain killers in management of acute post-operative period as well as on discharge from the hospital compared to opioid medications for postoperative pain following URS and stent placement. The objective of this study will be to compare the pain control effects of no opioid and opioid pain killers during the post-operative period. This study will be a Randomized Clinical trial. Data will be collected from department of Urology, PKLI, Lahore. All patients included in this study will undergo ureteroscopic laser lithotripsy of ureter stones. One group will receive tramadol (opioid) while other two groups will receive Paracetamol and diclofenac sodium (NSAIDs) respectively. All subjects will receive one of the three pain killers after ureteroscopy procedure for ureter stones in a randomized fashion. Postoperative pain intensity will be measured by the investigator and the nurse in the first hour after the surgery in the recovery room and then in urology ward at 1,6, 12, 24, 48, & 72 hours using the Numeric Pain Intensity Scale (NPIS).A mean pain score of less than 2 for each category of surgical procedures or analgesics group will be defined as satisfactory pain control. The data will be analyzed using SPSS v 24.
Patients (female, male, or queer) with ureteral stones (smaller than 1 cm at the widest diameter of the stone) without pyonephrosis, urinary sepsis, or untraceable pain will be enrolled into the study. Ureteral width at the smallest area of the ureter (in most cases UV junction) will be noted during regular ultrasound scans. The ratio of ureteral width to the stone diameter will be correlated with the spontaneous stone passage.
Ureteric calculi are one of the most common reasons for frequent Urolithiasis. The estimated prevalence is 8-13% of all calculi. Medical expulsive therapy (MET) is recommended by the European Association of Urology (EAU) (2013) for 5-10 mm ureteric stones to facilitate stone passage. For MET, alpha blockers, mainly tamsulosin, have shown efficacy in several randomized controlled trials. The underlying pathophysiology of this therapy is supported by the presence and distribution of adrenoreceptors in the ureter. Blocking the action of alpha-1 receptors by pharmacological agents (alpha blockers), such as alfuzosin, terazosin, doxazosin, and, most typically, tamsulosin, results in the relaxation of the ureteric smooth muscle. Ureteroscopy (URS) is the most commonly performed procedure for the treatment of ureteral calculi, with a high (>90%) stone-free rate after a single treatment. Advancing a rigid ureteroscope into a non-dilated ureter may be difficult and cause complications. Ureteric dilatation may provide access to stones, but not in all cases, and ureteral mucosal injury up to perforation might occur.
