ABSTRACT
OBJECTIVE@#To compare the efficacy and safety of endoscopic laser lithotripsy (LL) and endoscopic pneumatic lithotripsy (PL) for ureteral stones.@*METHODS@#We retrospectively analyzed the clinical data of 415 patients with ureteral calculi treated with endoscopic laser lithotripsy (n = 214 ) and pnumatic lithotripsy (n = 201 ).@*RESULTS@#The overall successful fragmentation rate of all ureteral stones in a single session of the LL group was higher than that of the PL group (95% vs. 69%, P < 0.01). The average stonefree time of the LL group was shorter than that of the PL group (18 days vs. 31 days, P < 0.01). No complications such as perforation during the operation were observed in the LL group whereas 3 perforations occurred in the PL group.@*CONCLUSION@#LL has its advantage over PL in its better clinical effect for the stone fragmentation and low complication rate and is an effective and safe treatment for ureteral stones.

<p><b>OBJECTIVE</b>To evaluate the elective method and the clinical experience of using appendix in situ in continent urinary diversion.</p><p><b>METHODS</b>26 continent urinary diversions have been performed since 1990. Among them, 11 cases underwent the intussuscepted technique and other 15 cases underwent embedded technique.</p><p><b>RESULTS</b>The continent rate was 100% at the daytime among all the case, while intermittent incontinence occurred in 3 cases at night, which happened in the intussuscepted group. Other complications included catheterization difficulty in 3 cases, appendix perforation in 1 case, which happened in the embedded group, traction of the appendix into abdominal cavity in 1 case, and prolapse of the intussusepted appendix in 3 cases.</p><p><b>CONCLUSIONS</b>The embedded technique shows better results than the intussuscepted technique in term of continence. The embedded technique, using appendix in situ as an efferent loop, shows the advantages of easily performing, timesaving, better outcome in continence and less complication. We believe the technique of appendix in situ as an efferent loop is an ideal modality in urinary diversion operation.</p>
