struvite and Hydronephrosis

Encrusted cystitis is a very rare chronic inflammatory disease of the bladder characterized by precipitation and incrustation of phosphate and ammonium-magnesium salts on the vescical mucosa, caused by urinary infection due to urolithic microorganisms. Corynebacterium urealyticum or Corynebacterium group D2, a multiple antibiotic-resistant urea-splitting bacterium, is the most frequently incriminated aetiology. We report a case of a 57-year-old man affected by systemic erythematosus lupus with a long history of dysuria and suprapubic pain who underwent percutaneous nephrostomy drainage with urethral stenting for lupoid obstructive uropathy. Before the diagnosis of encrusted cystitis by Corynebacterium urealyticum was established, the patient underwent five cystoscopies to remove the plaques and multiple unsuccessful antibiotic treatment courses. Eventually the infection was definitively cured after a two-week course with intramuscular teicoplanin.

To assess the clinical outcome of a ferret undergoing a ureteroneocystostomy for treatment of urolithiasis.. A 10-month-old spayed female ferret.. The ferret was evaluated for straining to urinate and defecate, hematochezia, and a rectal prolapse. Plain radiographs revealed large cystic and ureteral calculi. Clinicopathologic analyses indicated the ferret was anemic with an elevated creatinine concentration. Exploratory laparotomy defined bilateral ureteral calculi that were unable to be successfully moved into the bladder. A cystotomy was performed to remove a large cystic calculus. Serial abdominal ultrasonographic examinations showed progressive hydronephrosis of the left kidney and persistent pyelectasia of the right kidney secondary to bilateral ureteral calculi. This confirmed a left ureteral obstruction secondary to the distal calculus while the right ureter remained patent.. A ureteroneocystostomy was performed to allow for left renal decompression. The ferret recovered well despite worsening hydronephrosis of the left kidney in the perioperative period. The ferret was discharged from the hospital 10 days after initial evaluation. At 3-week follow-up, abdominal ultrasonography confirmed resolution of hydronephrosis and ureteral dilation of the left kidney and ureter.. A ureteroneocystostomy successfully allowed renal decompression and ureteral patency in a ferret with urolithiasis. To the authors' knowledge, this is the first time this procedure has been reported in a ferret for treatment of a ureteral calculus obstruction and may result in good long-term outcome.

Crossed fused renal ectopia is a rare renal anomaly. Formation of staghorn and struvite calculi within it has never been reported in local literature. A 25-year-old man with macrohematuria and right flank pain was admitted to the hospital. An intravenous pyelography revealed right sided crossed fused ectopic kidney showing a staghorn and struvite calculi in upper-moiety along with gross hydronephrosis. Patient was conservatively managed after exclusion of other congenital anomalies.
