Our surgical modifications included the \u201cwishbone\u201d anastomosis and \u201cureteral plate\u201d technique. Demographic, perioperative, and follow-up data were recorded and compared retrospectively between the groups. Success was defined as subjective pain alleviation and hydronephrosis improvement. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Thirteen modified laparoscopic flap pyeloplasty (mLFP) and 8 modified robotic flap pyeloplasty (mRFP) were performed successfully without conversion. mRFP tended to have shorter overall operative time (142.4 vs. 179.1 min, &lt;i&gt;p&lt;\/i&gt; = 0.122) and anastomosis time (43.1 vs. 61.0 min, &lt;i&gt;p&lt;\/i&gt; = 0.093) than mLFP. No difference was found in estimated blood loss (&lt;i&gt;p&lt;\/i&gt; = 0.723) and pararenal draining time (&lt;i&gt;p&lt;\/i&gt; = 0.175) between the groups. The mean postoperative hospital stay of mRFP was significantly shorter than that of mLFP (5.0 vs. 8.2 days, &lt;i&gt;p&lt;\/i&gt; = 0.015). No major complications occurred. During the mean follow-up of 17.9 months, the overall success rate was 90.5%, and there was no significant difference between 2 groups. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; The modified flap pyeloplasty could be considered a practical and effective treatment option with a high success rate for recurrent UPJO with a long proximal ureteral stricture, and the robotic procedures showed advantages of higher efficiency and faster recovery.
