Renal pelvis and ureteropelvic junction incarceration in a Grynfeltt-Lesshaft hernia: a case report and review of the literature

Radiological findings in a case of congenital lumbar herniation of the kidney with a spinal tube defect

The superior lumbar triangle is formed by the erector spinae muscles medially, internal oblique muscles laterally and the 12th rib superiorly. Herniation through this triangle can be congenital or acquired (primary or secondary). The contents of the hernial sac commonly include retroperitoneal fat, kidneys, ascending or descending colon, small intestines, stomach, spleen, etc. We present a case of an infant with congenital herniation of the left kidney through the superior lumbar triangle with an incidentally detected closed spinal tube defect. The anatomy of the lumbar triangle and a literature review of the associated hernia have been briefly described in this article.

A Case of an Atraumatic Posterior Perirenal Lumbar Hernia

Retroperitoneal lumbar hernias are a rare entity. Atraumatic posterior perirenal hernias are an exceptionally rare form of retroperitoneal lumbar hernias. Because of their infrequency, there are no standardized methods of surgical care for the treatment of atraumatic (primary spontaneous) posterior perirenal hernias. This report documents the finding and management of an atraumatic posterior perirenal lumbar hernia in a 69-year-old female.

Ultrasound Guided Percutaneous Nephrolithotomy in Mesh-Repaired Incisional Hernia

Objectives

To describe our technique of percutaneous nephrolithotomy (PNL) in patients with mesh-repaired flank incisional hernia. Polypropylene mesh which is used for fascia strengthening in hernia repair elicits intense inflammatory reaction and the consequent fibrosis alters the characteristics of abdominal wall. Thus, prior history of flank hernia repair with mesh may result in percutaneous nephrolithotomy failure.

Materials and Methods

Demographic data, renal stones characteristics, and any complication during surgery and follow-up of patients who were treated by PNL during 2011 to 2020 and had mesh in their flank region were collected.

Results

Percutaneous nephrolithotomy was performed without any problem in 8 patients with guide of ultrasonography.

Conclusion

Based on our experience, ultrasound-guided PNL is feasible and hypothetically superior to fluoroscopy in such circumstances.
