Research Philosophy

​

Mr Kucheria’s research interests reflect a practical approach to modern urology: using evidence to make treatment more effective, less invasive and more convenient for patients.

​

Particular emphasis is placed on developing minimally invasive techniques, improving stone-free rates, reducing complications and hospital stay, and ensuring that advances in surgical technology translate into meaningful improvements in patient care.

​

His research is undertaken within multidisciplinary and collaborative endourology teams and includes work with colleagues at Royal Free London and national and international specialist centres.

Research Areas

​

Mr Kucheria’s published and presented research has focused particularly on:

• Kidney and ureteric stone disease

• Supine PCNL

• Complex and staghorn renal stones

• ECIRS

• Flexible and diagnostic ureteroscopy

• Emergency definitive treatment of ureteric stones

• Cost-effectiveness of stone treatment

• Recurrent urinary tract infection

• Bladder epithelial changes

• Minimally invasive urological surgery

• Surgical consent and patient information

​

His more recent research has concentrated particularly on complex renal stone surgery, supine PCNL and ECIRS, reflecting his current specialist clinical practice. (London Urology Service)
