Concurrent bilateral emphysematous pyelonephritis and secondary iliopsoas abscess extending to thigh muscles with profuse rectal bleeding. A rare case scenario.

INTRODUCTION: Bilateral emphysematous pyelonephritis is exceedingly rare. CASE PRESENTATION: A 56 year old diabetic male presented with high grade fever 40o c, chills, and bilateral loin pain since two weeks a picture of septic shock. CT showed bilateral emphysematous pyelonephritis, the left kidney was smaller in size, the right renal unit showed marked hydronephrosis, right iliopsoas abscess extending to the thigh. The patient was managed by bilateral nephrostomy tubes and two retroperitoneal drains. Initially, the patient recovered, but the general condition deteriorated and profuse rectal bleeding occurred. Colonoscopy showed bleeding colonic mucosa. CONCLUSION: Bilateral emphysematous pyelonephritis is devastating disease that should be managed promptly to avoid septic shock.

A large renal bullet that resembles a large renal stone. A rare case scenario.

INTRODUCTION: Genitourinary trauma secondary to a gunshot wound is uncommon as it only occurs in about 10% of cases. We present a case of a gentleman who suffered a gunshot wound to the kidney. PRESENTATION OF CASE: A 28 year old man presented with irritative lower urinary tract symptoms (LUTs) since three months. The medical history was irrelevant. He is known case of neurogenic bladder maintained on regular clean intermittent catheterization (CIC). He has history of gunshot to the back since few years that resulted in spinal injury. CTUT showed retained bullet inside the right kidney that look alike hyperdense renal stone, Moreover, multiple vesical stones. The vesical stones were treated with cystolitholapaxy. Given that the patient is asymptomatic, conservative management for the retained right renal bullet is the feasible option. DISCUSSION: Based on the ASST classification, renal gunshot injury results in a grade IV injury. Abdominal exploration was reserved only in selected scenarios. Gunshot injuries to the kidney are commonly associated with thoracic and abdominal injuries. Gunshot injuries may be caused by low-velocity or high-velocity bullets. Given the paucity of cases reported in the literature, it is not obvious what is the optimum management of such patients with a retained renal bullet? We present the radiological findings and a clinical case summary as well for those who have Grade IV kidney injury and retained bullet managed conservatively. CONCLUSION: Retained renal bullet post gunshot injury to the back is unusual presentation. A characteristic star-like pattern produced by lead shots and not by "stone," consisting of plastic detonating cap will aid the urologist to differentiate retained renal bullet from renal stone. In such scenario, asymptomatic renal bullet look alike renal stone doesn't necessitate treatment.
