effects of an α blocker and terpene mixture for pain control and spontaneous expulsion of Ureter Stone
Korean Journal of Urology, 2007Co-Authors: Chong Won Bak, Sang Jin Yoon, Han ChungAbstract:Purpose: It was known that α-1 receptors are present in Ureteral smooth muscle. We aimed to reveal the effect of an α-blocker (tamsulosin) and terpene mixture (Rowatinex R ) on the expulsion of Ureter Stone (size less than 1cm), as well as its affect on the relief of pain. Material and Methods: The patients were classified into group A in which the size of the Ureter Stone less than 4mm (144 subjects) and group B in which the size of Stone was between 4mm and 10mm (48 patients). Each study group was also further divided into 3 sub-groups: group 1 with analgesics only, group 2 with Rowatinex R as well as analgesics, and group 3 with 0.4mg of tamsulosin as well as analgesics. Results: It was shown that the expulsion rates of Ureter Stone in sub-group 1 of group A, at the end of first week, was statistically lower (p<0.05) compared to that of sub-group 2 with Rowatinex R . It was also shown that compared to sub-group 1, the expulsion rate of Ureter Stone at the end of first week in sub-group 3 was statistically significant (p<0.05). Compared to the consumed amount of analgesics in group A, it was revealed that sub-group 2 and sub-group 3 used statistically fewer ampules of than sub-group 1 (p<0.05). Conclusions: Our study clearly showed that both α-blocker and Rowatinex R are effective means of controlling colicky pain and they speed up excretion of Ureter Stones that are less than 4mm in size, at the end of first week. Therefore, we conclude that an alpha-blocker and Rowatinex R

Holmium:YAG Laser Lithotripsy as a Treatment Modality for Ureteral Calculi
Korean Journal of Urology, 2008Co-Authors: Hyun Ho Hwang, Ro Jung Park, Kyung Hyun Moon, Sang Hyeon CheonAbstract:Purpose: We evaluated the results of Holmium:YAG laser lithotripsy according to the size and location of the Ureteral Stones. Materials and Methods: Between March 1998 and April 2007, the medical records of 203 patients who were treated with Ureteroscopic Holmium: YAG laser lithotripsy due to Ureteral calculi were reviewed. They were subgrouped by the size and the location of the Ureteral Stones. The results of treatment were evaluated by the Stone free rate and the mean operation time of each group. Results: The Stone free rates of the upper, mid and lower Ureter Stone groups were 73.3%, 96.1% and 100%, respectively. There was a significant difference in the upper Ureter Stone group compared to the other two groups, and especially for the group with Stone less than 10mm. Stone migration into the renal pelvis or calyx was a major cause of failure in the patients with upper Ureter Stones. 8 cases showed Stone migration and 2 cases showed fragment migration. Conclusions: As Holmium:YAG laser lithotripsy has a low complication rate and a high Stone free rate, it is an effective treatment modality for Ureteral calculi. However, such procedures should be performed carefully because the thermal effect of the Holmium:YAG laser causes Ureteral perforation, and especially in the cases of impacted or large Stones. Other effective alternatives such as trapping devices need to be studied for patients with upper Ureteral Stones to prevent Stone migration. (Korean J Urol 2008;49:60-65)

Xanthogranulomatous pyelonephritis: clinical experience with 21 cases
Journal of Infection and Chemotherapy, 2013Co-Authors: Sun Wook Kim, Byung Il Yoon, Dong Wan Sohn, Yong-hyun ChoAbstract:In this retrospective study, a review of the features of 21 recent cases of xanthogranulomatous pyelonephritis (XGP) is presented and compared with current published reports to improve the preoperative diagnosis. The clinical, laboratory, and radiological features, preoperative diagnoses, and operative methods of 21 patients with XGP were retrospectively reviewed. Mean age of the patients was 52.1 years; the female:male ratio was 2.5:1. All patients were symptomatic, and most common symptoms were flank pain and fever greater than 38°C. The laboratory results showed anemia in 71.4 % of cases, leukocytosis in 61.9 %, and pyuria in 81.0 %. In radiologic examinations, renal or Ureter Stone in 9 patients, hydronephrosis in 12 patients, a renal mass in 2 patients, and kidney enlargement in 9 patients were observed. For the patient who was suspected as having XGP before surgery, partial nephrectomy was performed; for 2 patients who were suspected as renal cell carcinoma, radical nephrectomy was performed; and for the remaining 18 patients, simple nephrectomy was performed. Among patients complaining of flank pain and fever, if the patients have a urinary tract infection and show the signs of anemia or leukocytosis and have staghorn calculi or a urinary tract obstruction and renal mass by radioactive examination, it is believed that the possibility of XGP should be considered.
