웅견의 요도결석에 대해서 실험견을 사용하여, 포피저부요도루조성술을 실시하고 4주후 병리조직학적 검사를 한 결과, 요도루작성에 있어서 가장 큰 어려움이었던 창구의 축소가 거의 없고, 음경백막과 요도점막의 유합상태가 좋은것을 확인하였으며, 이 수술방법을 임상에 활용하여 보았다.

A urinary calculus in the urethra is rarely seen and usually encountered in men with a urethral stricture or diverticulum. Herein, we report a rare case of a giant calculus in the urethra of a 42-year-old male patient with paraplegia after spinal cord injury due to car accident 20 years ago. A recent urologic consultation from the emergency room was performed since the patient had multidisciplinary symptoms during the day without any urination and presented with urinary difficulties due to hematuria and pain symptoms occurring with a mass in the bottom of the testicles. Abdomen and pelvic computed tomography (CT) was performed to examine the tumor mass, which was found to be absent. In addition, urethral stones were observed in the CT. Cystostomy was performed after the first urethroplasty, and the stone was removed from the urethra. Two weeks later, the patient was subjected to urethrography to remove the Foley catheter. No specific finding in voiding was detected. Giant urethral stones sometime require differentiation from tumor status. Treatment may vary according to size and location, requiring careful examination.

A one-month-old, 0.9 kg BW, male Korean Sapsal dog with anorexia, anuria, ataxia and depression was referred. On physical examination, the dog was showed tachycardia, hypothermia and pale mucous membrane. Hematologic values showed leukocytosis and mild anemia. Serum chemistry profile results revealed increased BUN (57.3 mg/dl) and $NH_3$ ($584\;{\mu}g/dl$), decreased albumin, sodium and potassium. Urinalysis showed hematuria, proteinuria, glucosuria, bacteriuria (Staphylococcus spp.) and magnesium ammonium phosphate crystalluria. On radiographic finding, urinary bladder was enlarged and 2 mm diameter radiopaque urolith was showed between os penis and prescrotal region. Urolithiasis was surgically corrected by urethrostomy.

A cross breed dog (6-year-old, 6 kg, intact male) was referred with hematuria. The dog had been treated for years owing to the urinary bladder calculi. On abdominal radiography, prostatic calculus was demonstrated in the prostatic area. In addition, ultrasonography and computed tomography (CT) scan would confirm that the part of calculus protruded within the prostatic urethra. The patient underwent a prostatolithotomy and traumatic prostatic urethra was carefully sutured and the omentum was filled with the prostate lumen. A crystallographic analysis of the stone showed 80% magnesium ammonium phosphate (struvite) and 20% carbonate apatite. The leakage of the urine was not observed post-operation and the hematuria improved and there was no specific problem at the 6 months follow-up.

This paper was performed to investigate the propensity of the diameter of maximum distended urethra from urethra to os penis in mature male dogs of 25 male dogs of different breeds. The measured sites of urethras were divided into 7 regions, i.e. prostate, membrane, isthmus, perineum, scrotum, prescrotum and os penis. By using the inflated balloon catheter filled with contrast medium, the maximum diameter of the distended urethras of each region was recorded and compared among regions. The mean diameter of the lumen from the prostatic urethra to the os penis urethra was gradually narrowed except for the isthmus portion, with a sense of resistance for retraction being noted at the level of ischiatic arch in 22 dogs. Proposed results from this should be utilized as a predictor of a treatment plan for the removal of urethroliths using an urohydropropulsion.

Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection(prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricutre, impacted stone, Cunningham clamp or condom catheter) and trauma(instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors. 1) a ureteral or bladder calculus that is lodged in the urethra, 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum conbined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

A 7-year-old castrated male Maltese developed anemia, ascites with peritonitis, and vomiting after urethrostomy. A microbial culture test of the peritoneal fluid indicated Candida albicans. Antifungal therapy was administered with intravenous fluconazole combined with antibacterial therapy. The patient recovered completely 37 days after referral admission.

A 9 year-old male Maltese with dysuria, pollakiuria, and stranguria was brought to the Veterinary Teaching Hospital, Chonnam National University. A right lateral abdominal radiograph was shown that 3 uroliths existed at the caudal aspect of the os penis and 5 uroliths existed in the passage of os penis. Uroliths were extracted by voiding urohydropropulsion and cystotomy in Maltese dog. The complication of cystotomy was hematuria, which might persist up to 2 days postoperatively but dysuria was not observed. So we applied voiding urohydropropulsion and cystotomy, and got a good prognosis. Gross examination of extracted uroliths were separated one from another but it was identified the same componet of calcium oxalate by stone quantitative analysis.
