AIMS OF STUDY: Present study designed to observe inhibitory effects of propiverine HC1 and tiropramide against the smooth muscle contraction of female rat bladder. Propiverine has both direct smooth muscle relaxation and anticholinergic effect and has relatively fewer side effect than conventionally used drugs such as oxybutinin. Tiropramide has been known as modulatory agents of gastrointestinal motility but also has inhibitory effects against the bladder contraction. METHODS: 30 adult female Sprague-Dawley rats were used. Bladder body above ureteral orifice was resected under pentobarbital anesthesia. 1 x 0.5 cm sized smooth muscle strip was made, and incubated in Tyrode`s solution aerated with 95% oxygen. After reaching equilibrium state, each strip was stimulated by field stimulation (FS, 1-32 Hz) and bethanechol administration (0.0000001-0.0001M). From each strip, degree of muscle contraction was recorded by physiograph (Gilson IC-MP). After the control stimulations, each strip was treated by atropine, tiropramide, oxybutinin and propiverine HC1. After 30 minutes, same stimulation were repeated and degree of muscle contraction was compared to pre incubation data. RESULTS: Frequency and dose dependent muscle contractions were noted for both FS and bethanechol stimulation. Greater degree of contractions were noted for FS than for bethanechol stimulation. Inhibitory effects of tiropramide, propiverine HC1 and oxybutinin were greater than those of atropine at FS (1-32 Hz). At high concentration (0.0001M), all of the drugs but atropine inhibited field stimulated smooth muscle contraction more than 90%. At lower concentration (0. 0000001-0.000001M), inhibitory actions of oxybutinin and propiverine HC1 were greater than that of tiropramide (p>0.05). Propiverine HC1 and oxybutinin had similar inhibitory effect for all con-centration. At higher concentration (0.0001M), inhibitory effects of tiro-pramide were more than 98% whereas those of oxybutinin and propiverine HC1 were 88%. At low concentration (0.0000001-0.000001M), oxybutinin exhibited greater inhibition against the bethanechol induced contraction than did tiropramide and propiverine HC1. With these results, it was suggested that in low concentration, oxybutinin and propiverine HCI had greater inhibitory effect than did tiropramide against smooth muscle contraction of the bladder. In high concentration though, tiropramide had superior inhibitory effect than did oxybutinin and propiverine HC1. Since, no difference was noted between oxybutinin and propiverine HC1 for the inhibitory action of bladder contraction, propiverine HC1 seems reasonable substitute for the treatment of detrusor hyperreflexia with less side effects. Also these results indicate that tiropramide can be used for the management of unstable bladder.

OBJECTIVE: The goal of this study was to determine the efficacy of caudal epidural injection in relieving pseudoclaudication of patients with lumbar spinal stenosis. METHOD: Fifteen patients with a spinal stenosis which was confirmed by the magnetic resonance imaging(MRI) studies, received a caudal epidural steroid injection of triamcinolone acetate 120 mg, in a solution mixed with 2 ml of 1% lidocaine, and 15 ml of normal saline. RESULTS: The visual analogue scales checked at 1 hour prior to injection, 1 hour postinjection, and 1 month postinjection were 8.1+/-0.8, 3.7+/-1.7, and 6.4+/-1.9, respectively. The exercise tolerance on the treadmill with 0o ramp inclination and 1.8 km/h speed was measured at 1 hour prior to injection, 1 hour postinjection, and 1 month postinjection. The time intervals to the first symptom of the pseudoclaudication were 2.3+/-0.8 minutes, 6.5+/-0.7 minutes, and 4.6+/-1.9 minutes, respectively. CONCLUSION: In our study, the caudal epidural injection offered a significant short-term relief for the pseudoclaudication. Also it appeared to be a reasonable therapeutic option among patients with lumbar spinal stenosis after 1 month postinjection.

Spinal subarachnoid hemorrhage (SAH) due to solitary spinal aneurysm is extremely rare. A 45-year-old female patient visited the emergency department with severe headache and back pain. Imaging studies showed cerebral SAH in parietal lobe and spinal SAH in thoracolumbar level. Spinal angiography revealed a small pearl and string-like aneurysm of the Adamkiewicz artery at the T12 level. One month after onset, her back pain aggravated, and follow-up imaging study showed arachnoiditis. Two months after onset, her symptoms improved, and follow-up imaging study showed resolution of SAH. The present case of spinal SAH due to rupture of dissecting aneurysm of the Adamkiewicz artery underwent subsequent spontaneous resolution, indicating that the wait-and-see strategy may provide adequate treatment option.

PURPOSE: After correction of stress incontinence, some patients experience the improvement of overactive bladder symptoms. During urodynamic study of some patients, the leak point pressure has a tendency to decrease at increasing vesical volumes. We evaluated the possibility of a correlation between stress incontinence parameters and bladder capacity or compliance. MATERIALS AND METHODS: 113 stress incontinence patients who received urodynamic study from February 2000 to August 2005, were reviewed retrospectively for this study. In these patients, urodynamic stress incontinence parameters(abdominal leak point pressure: ALPP, maximum urethral closure pressure: MUCP), Q-tip angle and Stamey symptom grade and age were analyzed for a correlation with urodynamic cystometric capacity or compliance. We also compared the cystometric capacity of each symptom grade group to assess the difference among the groups. RESULTS: The mean age of the patients was 49.5+/-10.4 years(29~75), symptom grade was I(37), II(27), III(19), Q-tip angle was 33.6+/-14.0 degrees(10~60), cystometric capacity was 390.2+/-109.7 ml(121~641), compliance was 51.6+/-30.4 ml/cmH2O(9.2~142.5), ALPP was 83.2+/-31.0 cmH2O(24~200), MUCP was 55.4+/-29.3 cmH2O(7~142). In the correlation analysis, cystometric capacity had a correlation of -0.207 with age (p=0.029) and -0.215 with symptom grade(p=0.031). However, bladder compliance had no significant correlation with any of the parameters studied. In each symptom grade, cystometric capacity was 407.0+/-103.1 cc(I), 395.8+/-103.0 cc(II), 324.5+/-124.0 cc(III)(p=0.04) and the age for each symptom grade was 48.5+/-9.7(I), 48.1+/-10.1 (II), 57.3+/-10.1(III)(p=0.005). CONCLUSION: As cystometric capacity decreased, symptom grade of stress incontinence increased and age also increased. However, there were no other correlations between cystometric capacity or compliance and stress incontinence parameters.

PURPOSE: Intrarenal location of calculus significantly affects efficacy of SWL. In lower calyceal stone, its antigravitic location has been known to decrease success rate of SWL. In this study, renal calyceal stone is categorized according to its location and especially lower calyceal stone is further divided either with infundibulo-pelvic angle (IPA) greater than 90degreesor that with less than 90degrees. Difference of the treatment results were compared according to the location of stones. MATERIALS AND METHODS: 142 stones(upper calyx: 52, mid calyx: 11, lower calyx: 79) of 117 patients which had been treated by SWL since 1995 were retrospectively studied. The SWL machine used for treatment was EDAP-LT 01 Plus(piezoelectric mechanism with 3.5 MHz ultrasonic imaging system). Complete stone delivery was defined as state with no residual stone on KUB film. RESULTS: The mean stone size was 0.97+/-0.3cm and mean number of treatment session was 5.0+/-3.2. The complete stone delivery rate was 83%. There was no significant difference in number of session according to stone location(upper calyx: 4.4+/-1.9, mid calyx: 3.18+/-1.5, lower calyx: 4.8+/-2.4, p>0.05). The stone sizes of each calyx were 1.1+/-0.33cm, 0.8+/-1.5cm and 0.91+/-0.24 cm respectively. There were no siginificant differences in stone size among calyceal location(p>0.05). The complete stone delivery rate of each calyx were 88.5%(46/52), 90.9%(10/11), 74.7%(59/79) respectivey(p>0.05). Of the 79 lower calyceal stones, of which IPA was greater than 90degreesin 27 stones and less than 90degrees in 52 stones. There was no siginificant difference in size between two groups(0.86+/-0.16cm vs 0.9+/-0.25cm, p>0.05). The stone with greater infundibulo-pelvic angle had more session than that with lesser infundibulo-pelvic angle(4.9+/-2.2 vs 4.3+/-3.3, p=0.039). There was significant difference in complete stone delivery rate according to infundibulo-pelvic angle(96.3% - 26/27 vs 63.4% - 33/52, p=0.034). Also stone with less infundibulo-pelvic angle had inferior stone delivery rate compared with that of upper and mid calyceal stone. CONCLUSIONS: The lower calyceal stones with infundibulo-pelvic angle lesser than 90degreeshad significantly lower stone delivery rate compared with those with greater infundibulo-pelvic angle and upper and mid calyceal stone. In case of lower calyceal stone with infundibulo-pelvic angle less than 90degrees, other treatment such as PNL, pyelolithotomy must be considered as primary treatment modality.

Granulocytic sarcoma is an uncommon extramedullary tumor composed of granulocytic precursor cells such as myeloblasts or monoblasts. These tumor were originally called chloroman because of the green color imparted by the heavy concentration of the myeloperoxidase present in myelogenous leukemic cells. The tumor usually develops during the course of myelogenous leukemia or myeloproliferative disorders and may represent the initial manifestation of leukemia. Rarely, granulocytic sarcoma is recognized as an isolated tumor without any evidence of leukemia. We report a case of a 21-year-old man who was diagnosed as granulocytic sarcoma of right kidney after complete remission of acute myelocytic leukemia.

Surgical decompression for cervical radiculopathy includes anterior cervical discectomy and fusion, anterior or posterior cervical foraminotomy, and cervical arthroplasty after decompression. The aim of this study was to evaluate the usefulness of a CO2 laser in posterior-approach surgery for unilateral cervical radiculopathy. From January 2006 to December 2008, 12 consecutive patients with unilateral cervical radiculopathy from either foraminal stenosis or disc herniation, which was confirmed with imaging studies, underwent posterior foraminotomy and discectomy with the use of a microscope and CO2 laser. For annulotomy and discectomy, we used about 300 joules of CO2 laser energy. Magnetic resonance imaging (MRI) was used to evaluate the extent of disc removal or foraminal decompression. Clinical outcome was evaluated by using visual analogue scale scores for radicular pain and Odom's criteria. For evaluation of spinal stability, cervical flexion and extension radiographs were obtained. Single-level foraminotomy was performed in 10 patients and two-level foraminotomies were performed in 2 patients. Preoperative radicular symptoms were improved immediately after surgery in all patients. No surgery-related complications developed in our cases. Postoperative MRI demonstrated effective decompression of ventral lesions and widened foraminal spaces in all cases. There was no development of cervical instability during the follow-up period. Posterior foraminotomy and discectomy using a microscope and CO2 laser is an effective surgical tool for unilateral cervical radiculopathy caused by lateral or foraminal disc herniations or spondylotic stenosis. Long-term follow-up with radiographs showed no significant kyphotic changes or spinal instability.

Pediatric laparoscopic appendectomy is controversial particularly in complicated appendicitis. We evaluated the outcomes of laparoscopic appendectomy (LA) and open appendectomy (OA) in simple appendicitis and complicated appendicitis respectively. Since June 2004, initial LA has been our policy in all appendicitis including complicated ones. A total of 160 patients were included in this study, consisting of 80 OA (August 2001 . August 2003) and 80 LA (June 2004 . June 2006). We compared the operating time, the length of hospital stay, the length of antibiotics use, and the postoperative complications between LA and OA. In simple appendicitis (73), there were no differences between LA and OA. However in the 87 patients with complicated appendicitis, the operating time was longer in LA (64.8 min vs. 50.2 min) but the length of hospital stay was shorter in LA than OA (8.5 days vs. 9.6 days). There was one complication in simple appendicitis group and six in complicated appendicitis group (3 cases in LA, 3 cases in OA). There was no difference in the results of LA versus OA in simple appendicitis. Therefore for simple appendicitis, LA is recommended in consideration of the cosmetic effect (fewer scar). In complicated appendicitis, early discharge was an advantage and there were no differences in complications in LA despite a longer operative time. So we conclude LA can be considered as the first choice of treatment for all pediatric appendicitis including complicated appendicitis. To confirm our impressions, more well controlled randomized prospective studied need to be done.
