Two dogs were presented urinary disorder in the associated with urolithiasis. Clinical signs were increased frequency of urination with mild straining pollakiuria, general depression and anorexia. On physical examinations, the pain was revealed at the palpation of the urethral area. Urinalysis showed high specific gravity, high pH, and triple phosphates. Radiography showed an increased radiopacity, and ultrasonography showed hyperecho in the just behind of os penis. Urolithiasis was diagnosed on the basis of clinical signs, radiography, and ultrasonography. In the prescrotal urethrotomy, urethra on the midline was incised and uroliths were eliminated. After elimination of uroliths, incision area was closed with 4-0 synthetic absorbable suture. In postoperative, there was good prognosis without hemorrhage, inflammation, and urethral stricture.

Lesch-Nyhan syndrome is an inborn error of purine metabolism resulting from hypoxanthine-guanine-phosphoribosyltransferase (HGPRT) deficiency and leading to excess purine production and uric acid over-production. It is a very rare X-linked recessive disorder, characterized by movement disorder, cognitive deficits, and self-injurious behavior. However, because of the high incidence of calculi, patients may present for surgery of urinary tract, and have increased risk of difficult intubation, aspiration pneumonia, renal insufficiency or sudden death. We report the case of a 5-year-old boy with Lesch-Nyhan syndrome who underwent successive extracorporeal shockwave lithotripsy under general anesthesia.

We present the characteristic plain radiographic and intravenous urographic (IVU) findings of calculus formed over a hair. A 66-year-old man who had been quadriplegic for 40 years because of vertebral injury was admitted for further evaluation of frequent urinary tract infection. Plain radiography showed a linear, serpiginous calcification in the lower abdomen, and IVU revealed a round filling defect with linear radiopacity in the bladder, suggesting calculus. The gross appearance of the stone after extraction demonstrated that calcification had formed over a hair.

Objective: To compare the usefulness of unenhanced spiral CT (UCT) with that of excretory urography (EU) in patients with acute flank pain. Materials and Methods: Thirty patients presenting with acute flank pain underwent both UCT and EU. Both techniques were used to determine the presence, size, and location of urinary stone, and the presence or absence of secondary signs was also evaluated. The existence of ureteral stone was confirmed by its removal or spontaneous passage during follow-up. The absence of a stone was determined on the basis of the clinical and radiological evidence. Results: Twenty-one of the 30 patients had one or more ureteral stones and nine had no stone. CT depicted 22 of 23 calculi in the 21 patients with a stone, and no calculus in all nine without a stone. The sensitivity and specificity of UCT were 96% and 100%, respectively. EU disclosed 14 calculi in the 21 patients with a stone and no calculus in eight of the nine without a stone. UCT and EU demonstrated secondary signs of ureterolithiasis in 15 and 17 patients, respectively. Conclusion: For the evaluation of patients with acute flank pain, UCT is an excellent modality with high sensitivity and specificity. In near future it may replace EU.

과거 방광결석으로 진단되어 처방식으로 관리 중인 6살의 잡종견이 혈뇨 증상을 주증으로 전남대학교 동물병원에 내원하였다. 환축은 복부 방사선 검사 결과 전립선 위치에 결석이 확인되었고, 초음파 검사와 CT 검사 결과 전립선 내 결석이 전립선 요도 내강으로 돌출되어 있음을 확인하였다. 환축은 prostatolithotomy를 통해 전립선 내 결석을 제거한 후 찢어진 전립선 요도를 봉합하였고, 결석에 의한 전립선 내강은 omentum을 채워 넣은 후 봉합하였다. 결석의 성분 분석을 위해 crystallographic analysis를 시행한 결과 결석은 magnesium ammonium phosphate (struvite) 80%와 carbonate apatite 20%로 구성되어 있음을 확인하였다. 환축은 수술 후 회복하여 뇨의 누출은 관찰되지 않았고, 혈뇨 증상은 개선되었으며, 수술 후 6개월에도 특별한 임상증상은 없었다.

Purpose: Augmentation cystoplasty (AC) is a surgical procedure used in adults and children with refractory bladder dysfunction, including a small bladder capacity and inadequate bladder compliance, and in whom conservative and medical treatment has failed. This study was aimed to determine the long-term outcomes of AC in children. Methods: A retrospective analysis was conducted of 42 patients (31 males; mean age, $14.2{\pm}6.2years$) who underwent AC for neurogenic and nonneurogenic bladder dysfunction, with a median $12.0{\pm}1.5years$ of follow-up. All patients underwent AC using the ileum with or without continent reconstruction. Pre-AC, concurrent, and post-AC procedures and complications were analyzed. Patients who underwent ureterocystoplasty, were lost to follow-up, or had less than 10 years of follow-up were excluded. The primary outcomes were the complication and continence rates, the post-AC linear rate of height and weight gain, and renal function. The Student t-test was used to evaluate between-group differences and the paired t-test was used to evaluate longitudinal changes in measured variables. Results: Renal function was stable or improved in 32 of 42 patients (76.2%), with a post-AC continence rate of 88.1%. Thirty patients (71.4%) required 72 procedures post-AC. There was no statistically significant difference in the mean percentile of height (P=0. 212) or weight (P=0.142) of patients in the pre- and post-AC periods. No cases of bladder perforation or malignancy were detected. Conclusions: We consider AC to be a safe and effective procedure that does not negatively affect future physical growth, while achieving a good rate of stable renal function. Patients need long-term follow-up to address long-term complications.

Background: This study was conducted to compare the effectiveness of low-dose ketamine versus ketorolac in pain control in patients with acute renal colic presenting to the emergency department (ED). Methods: This is a double-blind randomized clinical trial. The initial pain severity was assessed using the numerical rating scale (NRS). Then, ketamine or ketorolac was administered intravenously at a dose of 0.6 mg/kg and 30 mg respectively. The pain severity and adverse drug reactions were recorded 5, 15, 30, 60, and 120 min thereafter. Results: The data of 62 subjects in the ketamine group and 64 patients in the ketorolac group were analyzed. The mean age of the patients was $34.2{\pm}9.9$ and $37.9{\pm}10.6\;years$ in the ketamine and ketorolac group, respectively. There was no significant difference in the mean NRS scores at each time point, except for the 5 min, between the two groups. Despite a marked decrease in pain severity in the ketamine group from drug administration at the 5 min, a slight increase in pain was observed from the 5 min to the 15 min. The rate of adverse drug reactions, including dizziness (P = 0.001), agitation (P = 0.002), increased systolic blood pressure (> 140 mmHg), and diastolic blood pressure (> 90 mmHg) was higher in the ketamine group. Conclusions: Low dose ketamine is as effective as ketorolac in pain management in patients with renal colic presenting to the ED. However, it is associated with a higher rate of adverse drug reactions.

세대 및 특징이 다른 쇄석기종의 치료효과와 안전성을 비교하기 위해 2세대 Northgate사의 SD-3 쇄석기와 3세대 Storz사의 Modulith SLX 쇄석기로 체외충격과 쇄석술을 시행한 단일요로결석 환자 2000례를 분석한 결과, 치료효과를 판정해 볼 수 있는 요로결석의 위치 및 크기에 따른 성공률과 재시행률에서는 큰 차이가 없는 것으로 분석되어, 제 3세대 쇄석기인 Modulith SLX와 Northgate SD-3의 치료효과는 비슷한 것으로 나타났다. 그리고, 두 쇄석기종 모두에서 심각한 합병증의 발생은 없었으나, Northgate SD-3에서 Modulith SLX 보다 합병증으로 인한 입원치료를 받은 환자의 수가 많았다. 이상으로 두 기종 사이의 치료효과에는 큰 차이가 없고, Modulith SLX률 이용한 체외충격파쇄석술이 조금 더 안전한 것으로 나타났지만 두 기종의 장단점을 서로 보완하여 사용한다면 더욱 효과적인 치료방법이 될 것으로 생각된다.
