ABSTRACT

Purpose: Description of a clinical case of surgical treatment of nontraumatic rupture of the renal calyx fornix, with extravasation of contrast agent into the perirenal tissue.

Material and methods: Provided surgical treatment to a patient with spontaneous rupture of the calyx fornix on the background of ureteral obstruction caused by a stone.

Results: Considering the concomitant pathology in the form of obstructive pyelonephritis, it was decided to drain the upper urinary tract with an external stent. After 7 days, the patient underwent replacement of the external stent with the internal one. The patient underwent antibacterial, anti-inflammatory therapy, with a positive clinical, laboratory effect. Retrograde pyelography was performed 7 days later. Violations of the integrity of the cavity system of the left kidney were not revealed. The external stent was replaced with an internal one. After 2 months, ureterolitho-extraction was performed on the left.

Conclusion: From the data of the world literature and our own experience, we can conclude that spontaneous, non-traumatic rupture of the fornix is an extremely rare, urgent urological disease. We assume that the development of this process is similar to the Burhave syndrome, since smooth muscle fibers are present in the esophagus as well as in the esophagus. In order to provide immediate assistance to such patients, it is necessary to urgently drain the upper urinary tract. Timely diagnosis of this condition requires rapid tactics in the form of immediate ultrasound, radiological diagnostic methods, as well as computed tomography. The operational manual on the removal of stones in this case should be postponed for 2–3 weeks.

Keywords: rupture of the renal cup, spontaneous rupture of the calyx, kidney injury, urinary extravasation, urinoma, kidney stones
