It may be caused by serious hydronephrosis, weakened renal pelvis contractility and postoperative obstruction. J tube can be placed for 3 months. If this situation still occurs, retrograde radiography is needed to see whether the surgical anastomosis is narrow or not. Laparoscopic surgery is mild and requires high quality of pelvis and ureter. Otherwise, anastomotic stenosis, poor urination and abdominal pain are easy to occur.

Dr. Wang Zengjun solemnly reminded me that I couldn't fully understand the illness because I couldn't see the patient face to face. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
