A 9-year-old SF DSH was presented for evaluation of lower urinary tract signs that had not responded to antibiotic therapy. Physical examination was within normal limits. Urinalysis showed normal SG, hematuria, and proteinuria. Serum biochemistry showed normal urea, creatinine, and SDMA.
Urethritis and urethral sand and small calculi.
Retrograde and antegrade flushing would be recommended with ultrasound guidance at the time of surgery to ensure that complete liberation of the urethral calculi is achieved as some appeared to be embedded within the mucosal layers. It may be difficult to completely liberate. The remainder of the abdomen is unremarkable. Sand analysis and culture would be recommended.
The bladder itself was unremarkable. The pelvic urethra presented multiple small calculi and sand within the urethra with uniform thickening. There was no evidence of neoplasia. However, portions of the sand appeared to be slightly embedded within the urethra itself.
