Kidney Stone & Endourology Center
Established in 2017, the Center is leading minimally invasive stone surgeries and provides personalized treatments for complete control of urinary calculi by using shock wave lithotripsy, flexible ureteroscopy and percutaneous nephrolithotomy.
The mission is to boost the confidence in people for managing and treating urinary stones and hypertrophied prostate and ultimately increase patients' Quality of Life.

Listening carefully to otheres and working together to achieve goals.
Stone Treatments / 결석치료법
Shockwave Lithotripsy (SWL)
Up to now, shockwave lithotripsy (SWL) was the first choice in cases of renal stones of size < 20 mm and is generally performed in an outpatient department with the patient under local or general anesthesia.
However, SWL is not appropriate to patients with very hard stones and resistance to breakage with SWL, stones invisible on X-ray, (such as cystine, monohydrate or uric acid stones), and very large stones. Additionally, patients who are on blood-thinning medications or who may be pregnant should not undergo SWL procedures.
Retrograde Intrarenal Surgery (RIRS)
RIRS (retrograde intrarenal surgery) is a surgical procedure for management of renal stone or tumor. Urologists perform surgery within the kidney using a flexible ureterorenoscope. Therefore, this procedure is also called as 'flexible transurethral lithotripsy (f-TUL)'.
This endoscope is placed through the urethra, bladder, ureter and the urine-collecting part of the kidney. We call this a retrograde approach. Renal stones or tumors can be observed through the endoscope, removed by a laser and a small basket.

Percutaneous Nephrolithotomy (PCNL)
PCNL (percutaneous nephrolithotomy) is another surgical procedure for management of renal stones. Urologists can remove large and complex renal calculi using a single or multiple holes in the flank area of patients. The conventional size for each hole is 1 cm and these can induce bleeding, postoperative pain, and potential renal damage in limited cases.
The PCNL can be performed with a miniaturized endoscope via a smaller percutaneous tract (<6mm). This was named as "minimally invasive" or mini-PCNL.

Decision - ESWL vs. Surgery
ESWL vs. Surgery (PCNL, RIRS)
When you consider active removal of urinary stones, ESWL would be the first option.
However, in cases of multiple, large, or hard stones that cannot easily be removed by ESWL, you woldd consider the surgical treatment of RIRS or PCNL.
You should also consider surgery if you are under special situations/conditions such as planning a trip abroad, taking anticoagulant drugs, or having some unfavorable anatomy to spontaneous stone passage.
Decision - RIRS vs. MPCNL
RIRS vs MPCNL
Until now, there have been no definite indications that differentiated RIRS and MPCNL. However, you would consider (M)PCNL when you have large or staghorn stones, ureteral narrowing or abnormality, history of undergoing ileal conduit, or etc.
MPCNL and RIRS are safe and feasible surgical options for managing small-to-mid sized stones; the roles of these operations are expanding.
