A Prospective Assessment of the Perioperative Parameter and Treatment Outcomes of Urinary Calculi - International Registry

Renal stone is a common condition, and many patients suffered from recurrent diseases and required multiple interventions in their lifetime. Currently, there are many treatment options available for stone treatment, including shockwave lithotripsy, ureteroscopy, percutaneous nephrolithotomy etc.

Different treatment approaches will result in different treatment successful rate and also potential adverse effects to patients. The main challenge for stone management is the decision on the best treatment approach for individual stone of each patient. This is because for the same type of stone (such as lower caliceal stone or upper ureteric stone), different surgical treatment could be applied. The decision will depend on various patients (such as age, premorbid etc.) and stone factors (such as size, density etc) and also patients' preference.

New advances in technology have improved treatment outcomes for urolithiasis, such as single use flexible ureteroscopes, flexible and navigable ureteral access sheaths (FANS), direct in scope suction (DISS), intrarenal pressure (IRP) and intrarenal temperature (IRT) monitoring devices, new lasers and pulse modulation, etc.

Therefore, in order to have more information to guide treatment decision during discussion with patients, a prospective data registry is created to assess the treatment outcomes and complications of different treatment approaches in our hospital clusters. This information will be important for audit, treatment comparison and also patient education.
