Kidney stone surgery (lithotripsy)

Kidney and urinary stones are a common condition, responsible for sometimes intense pain (renal colic). When stones do not pass spontaneously or cause complications, surgical treatment becomes necessary. Current techniques are overwhelmingly minimally invasive. Laser lithotripsy, performed during ureteroscopy, fragments the stone into fine dust or small pieces that are extracted or passed naturally. The procedure is carried out through the natural passages, without any incision. The choice of technique depends on the size, location and composition of the stone, as well as the patient's anatomy. A metabolic work-up may be proposed later on to understand the origin of the stones and prevent recurrence through simple measures, particularly good hydration. At Clinique Pasteur Tunis, stone treatment benefits from a complete technical platform: flexible and rigid ureteroscopes, a lithotripsy laser and intraoperative imaging, allowing effective management tailored to each situation.
