Spontaneous perforation of the uterus and intravesical intrauterine device (IUD) is very rare. The treatment options for an intravesical IUD are open surgery or cystoscopic removal. Open surgery has been used generally for the removal of IUDs with formation of big stones or partial penetration of the bladder wall. In this case, we removed an IUD (multiload Cu 375®) with calculus that had sunk deeply into the bladder wall via laparoscopic partial cystectomy.

We investigated performance parameters of disposable flexible ureterorenoscopy (LITHOVUE) in patients with renal stones in a prospective, multicenter, observational study. Sixty two patients who underwent ureterorenoscopic surgery by LITHOVUE were included. Surgeons using a numerical scale, evaluated the maneuverability of the scopes and general perceptions of visibility related to the monitor and irrigation systems. General pain and fatigue scores were evaluated and compared to existing scopes. Mean patient age was 57.3 years and stone size was 15.4 mm. Clinical success of overall stone removal was 82.3%. Complications occurred in 4 cases of the Clavien classification grade I in a single case and II in 3 cases. Comparative parameters of maneuverability, perception of the monitor system and perception of the irrigation channel were 2.5, 2.5, and 3.0, respectively. The most favorable evaluation of physical strain was about ‘shoulder fatigue’ and ‘hand fatigue’. Unfavorable evaluations were recorded for ‘wrist stiffness’ and ‘thumb fatigue’. Maximal deflection angles of 270° were preserved in 53 cases (85.5%). No pre-stenting procedure and the longer operative time were significant predictors of poorly-preserved deflection angles <270°. LITHOVUE showed good maneuverability and perception scores for the monitor and irrigation systems. LITHOVUE received favorable evaluations on pain and fatigue scores.
