ObjectiveRetrospectively analyzed with various clinical indicators of the retroperitoneal laparoscopic dismembered pyeloplasty with two different technique of JJ stenting in different age paragraph children. Approach the technique of JJ stenting which is appropriate for different age paragraph children.MethodsCollect the 68 cases of children (age<14) in our hospital from Jun 2005 to Dec 2010 which adopt retroperitoneal laparoscopic dismembered pyeloplasty, according to the first choice of catheter method grouping. There are 27 cases children (age<6),12 cases of antegrade stenting (A) group) and 15 cases of improved stenting (B1 group). There are 41 cases children (6<age<14),23 cases of antegrade stenting (A2 group) and 18 cases of improved stenting (B2 group). Stent insertion time, operative time, stent correctly positioned, postoperative hospital stay, time of postoperative drainage, total hospital charges, major complications, follow-up information were compared between the two groups retrospectively.ResultsLess than 6 years old, the two groups in the operative time,postoperative hospital stay, time of postoperative drainage, total hospital charges was no significant difference (P>0.05), the two groups in the stent insertion time, stent correctly positioned, major complications were significant difference (P<0.05).6-14, the two groups in the stent correctly positioned, postoperative hospital stay, time of postoperative drainage, total hospital charges major complications was no significant difference (P>0.05), the two groups in the stent insertion time, operative time were significant difference (P<0.05). The correctly positioned of antegrade stenting increase with age, there is a rising trend, improved group in each age stent correctly positioned were higher, almost up to 100%.Conclusions1. Improved stenting in retroperitoneal laparoscopic pyeloplasty of the less than 6 years old, the rate of stent correctly positioned is up to 100%. And relative to antegrade stenting, improved stenting did not significantly increased operation time and total hospital charges, that is a ideal catheter method suitble to chlidren less than 6.2. Antegrade stenting in retroperitoneal laparoscopic pyeloplasty of the 6 to 14, the rate of stent correctly positioned is higher. And relative to improve stenting, it has the advantage of operation time.3. Note action gently, avoid injury ureteral cause under section of ureteral stricture when antegrade stenting in children.4. Select appropriate catheter method according to age and performer personal experience in children, in favour of improving the rate of stent correctly positioned and reducing catheter related complications.
