Insights
Pelviureteric junction (PUJ) obstruction can cause abdominal pain. A case report details a laparoscopic pyeloplasty where an appendix with adhesions was found to be a dual pathology contributing to the obstruction.
Area of Science:
- Urology
- Surgical Case Reports
Background:
- Pelviureteric junction (PUJ) obstruction is a common condition in adults and children.
- Congenital anomalies and crossing renal vessels are frequent causes of PUJ obstruction.
Observation:
- A young woman presented with intermittent abdominal pain and right-sided hydronephrosis.
- Laparoscopic Anderson-Hynes pyeloplasty was planned for the diagnosed PUJ obstruction.
Findings:
- During surgery, a partly extraperitoneal appendix with adhesions was found adhered to the ureter below the obstructed PUJ.
- The appendix and its adhesions were identified as a likely dual pathology contributing to the patient's symptoms.
Implications:
- This case highlights the importance of considering atypical causes of PUJ obstruction.
- Concurrent appendectomy during pyeloplasty may be beneficial in select cases with dual pathologies.
Abstract:
Pelviureteric junction (PUJ) obstruction is a condition frequently encountered in both adult and pediatric patients. Congenital abnormalities and crossing lower-pole renal vessels are the most common underlying pathologies in both men and women. This report presents a case of a young woman who was complaining of intermittent abdominal pain in whom right-sided hydronephrosis was diagnosed. The patient was scheduled for a laparoscopic right-sided Anderson-Hynes pyeloplasty. During the procedure a partly extraperitoneal appendix, with extensive adhesions to the posterior abdominal wall abutting on the ureter just below the obstructed PUJ, was identified. The patient underwent dismembered laparoscopic Anderson-Hynes pyeloplasty with concurrent appendectomy for likely dual pathologies being responsible for her symptoms.
