Objective: Pelvic floor muscles (PFMs) form the base of the abdomino-pelvic cavity and also the PFMs function is important for urinary continence. PFMs training (PFMT) is considered to be the first method for PFM dysfunction. This study demonstrated correct PFMs contraction among commonly used different contraction methods for PFMT. Design: Cross-sectional study. Methods: In this study, nineteen middle-aged (40-70 years) women participated. To evaluate PFM function, ultrasonography was used to measure the distance of the bladder base movement. The distance of the PFM movements were calculated at rest and during the other contractions. The following four different contraction methods were performed randomly: (1) PFM contraction, (2) abdominal drawing-in maneuver (ADIM), (3) anal contraction, and (4) hip adductor muscle contraction. The participants held the contraction for 3 seconds for a total of 3 times with a 30 seconds rest period between each trial. The mean of three measurements in each position were obtained and compared with that in the resting position. Results: The bladder base movement values were significantly greater when comparing PFM with ADIM and hip adductor contractions (p<0.05). The bladder base movement values were significantly greater when comparing ADIM and anal contractions with hip adductor contractions (p<0.05). Conclusions: The results of this study suggest that performing PFM contractions is the best method among the common methods for PFMT. Performing PFM contractions was more effective than the other contraction methods.

Effects of L-arginine and NG-nitro-L-arginine methyl ester (L-NAME) on the renal dysfunction that is induced by cisplatin (CDDP) were investigated. A single dose of CDDP (7.5 mg/kg i.p.) induced renotoxicity, which was manifested by increasing the sensitivity of isolated urinary bladder rings to acetylcholine (ACh), together with a significant elevation of serum urea and creatinine, and a severe decrease in serum albumin. Moreover, renal dysfunction was further confirmed by a significant decrease of enzyme activities, such as glutathione peroxidase, GSH-Px (E.C 1.11.1.9), catalase (E.C 1.11.1.6), as well as a significant increase in lipid peroxides that were measured as malondialdhyde (MDA) in kidney tissue homogenates. The administration of L-arginine (70 mg/kg/d p.o in drinking water 5 d before and 5 d after the CDDP injection) significantly ameliorated the renotoxic effects of CDDP, as judged by restoring the normal responses of isolated bladder rings to Ach, and also by an improvement in a range of renal function indices, which included serum urea and creatinine concentrations and kidney weight. In addition, L-arginine prevents the rise of MDA, as well as a reduction of GSH-Px and catalase activities in kidney tissues homogenates. On the other hand, the administration of L-NAME (4 mg/kg/d p.o) resulted in no protection against renal dysfunction that was induced by CDDP treatment. The findings of this study suggest that L-arginine can attenuate kidney injury that is produced by CDDP treatment. In addition, L-arginine may be a beneficial remedy for CDDP-induced renal toxicity, and could be used to improve the therapeutic index of CDDP.

Tonic smooth muscle exhibit the latch phenomenon: high force at low myosin regulatory light chains (MRLC) phosphorylation, shortening velocity (Vo), and energy consumption. However, the kinetics of MRLC phosphorylation and cellular activation in phasic smooth muscle are unknown. The present study was to determine whether $Ca^{2+}$-stimulated MRLC phosphorylation could suffice to explain the agonist- or high $K^+$-induced contraction in a fast, phasic smooth muscle. We measured myoplasmic [$Ca^{2+}$], MRLC phosphorylation, half-time after step-shortening (a measure of Vo) and contractile stress in rabbit urinary bladder strips. High $K^+$-induced contractions were phasic at both $22^{\circ}C$ and $37^{\circ}C$: myoplasmic [$Ca^{2+}$], MRLC phosphorylation, 1/half-time, and contractile stress increased transiently and then all decreased to intermediate values. Carbachol (CCh)-induced contractions exhibited latch at $37^{\circ}C$: stress was maintained at high levels despite decreasing myoplasmic [$Ca^{2+}$], MRLC phosphorylation, and 1/half-time. At $22^{\circ}C$ CCh induced sustained elevations in all parameters. 1/half-time depended on both myoplasmic [$Ca^{2+}$] and MRLC phosphorylation. The steady-state dependence of stress on MRLC phosphorylation was very steep at $37^{\circ}C$ in the CCh- or $K^+$-depolarized tissue and reduced temperature flattend the dependence of stress on MRLC phosphorylation compared to $37^{\circ}C$. These data suggest that phasic smooth muscle also exhibits latch behavior and latch is less prominent at lower temperature.

Background: Urinary bladder cancer is a common malignancy in the West and ranks as the $7^{th}$ most common cancer in our region of Kashmir, India. FGFR3 mutations are frequent in superficial urothelial carcinoma (UC) differing from the RAS gene mutational pattern. The aim of this study was to analyze the frequency and association of FGFR3 and RAS gene mutations in UC cases. Materials and Methods: Paired tumor and adjacent normal tissue specimens of 65 consecutive UC patients were examined. DNA preparations were evaluated for the occurrence of FGFR3 and RAS gene mutations by PCR-SCCP and DNA sequencing. Results: Somatic point mutations of FGFR3 were identified in 32.3% (21 of 65). The pattern and distribution were significantly associated with low grade/stage (p<0.05). The overall mutations in exon 1 and 2 in all the forms of RAS genes aggregated to 21.5% and showed no association with any clinic-pathological parameters. In total, 53.8% (35 of 65) of the tumors studied had mutations in either a RAS or FGFR3 gene, but these were totally mutually exclusive in and none of the samples showed both the mutational events in mutually exclusive RAS and FGFR3. Conclusions: We conclude that RAS and FGFR3 mutations in UC are mutually exclusive and non-overlapping events which reflect activation of oncogenic pathways through different elements.

Aim: To study the causes and significance of both microscopic and macroscopic haematuria in adult patients and assess possible relevance to early detection of urological cancers. Methods: 417 patients presenting with haematuria were assessed in our Urology Unit. Following confirmation of haematuria, these patients were subjected to imaging techniques and flexible cystoscopy. Parameters analysed included clinical characteristics, imaging results, flexible cystoscopy findings, time delay to diagnoses and eventual treatment and final diagnoses of all cases. Results: 390 haematuria cases were analysed from 417 consecutive patients with haematuria. After 27 cases were excluded as they had previous history, 245 microscopic and 145 macroscopic. Age range was 17 to 95 years old with predominance of 152 females to 239 males. The racial distribution included 180 Chinese, 100 Indians,95 Malays and 15 other races. The final diagnoses were benign prostatic hyperplasia (22.6%), no cause found (22.3%), other causes (18.7%), urolithiasis (11.5%), urinary tract infection UTI (10.8%), non specific cystitis (10.3%), bladder tumours (2.8%) and other genitourinary tumours (1%). 11 new cases (2.8%) of bladder cancers were diagnosed, with a mean age of 59 years. Only 3 of 245 (1.2%) patients with microscopic haematuria had newly diagnosed bladder tumour compared with 8 of 145 (5.5%) patients with frank haematuria (p=0.016). Mean time taken from onset of symptoms to diagnosis of bladder cancer was 53.3 days with definitive treatment (TURBT) in 20.1 days from diagnosis. Conclusion:- This study has highlighted the common causes of haematuria in our local setting. We recommend that full and appropriate investigations be carried out on patients with frank haematuria especially those above 50 years old in order to provide earlier detection and prompt management of bladder diseases especially tumours.

목 적 : 요로 결석은 소아에서 흔하지 않은 질환이나 요로 결석의 반복과 진행은 신 기능 저하를 초래하여 결국 만성 신부전으로 진행 될 수 있는 질환이다. 또한 성인과 달리 대부분 정확한 원인이 알려져 있지 않으나 요로 감염, 비뇨 생식기계의 해부학적 이상, 대사성 장애 등이 요로 결석 형성의 원인이 될 수 있다. 방 법 : 1998년 9월부터 2007년 7월까지 서울대학교 어린이병원 소아과에서 요로결석으로 진단받은 73명(남:여=42:31, 평균 연령 $6.6{\pm}5.3$세)을 대상으로 후향적으로 의무기록을 분석하였다. 결 과 : 소아 요로 결석의 주 증상은 육안적 혈뇨가 18명(25%)으로 가장 많았으며, 측복부 동통 또는 복통이 13명(18%), 두 증상이 동반된 환자 10명(14%) 순이었다. 결석의 위치는 상부 요로(신 및 요관) 결석이 48명(66%), 하부 요로(방광 및 요도) 결석의 경우는 18명 (24%)이었고, 상부 및 하부 요로 모두에 결석이 있는 경우는 2명(3%)이었다. 요 정체로 요로 감염을 일으킬 수 있는 구조적인 요인이 동반된 경우는 모두 30명(41%)이었으며, 요로 결석 형성과 관련된 대사 이상은 23명(32%)에서 발견되었다. 특별한 유발 인자가 없는 경우는 17명(23%)이었다. 결석 성분 분석상 감염석이 24명(67%)으로 가정 많았으며, 칼슘석 8명(22%), 요석 3명(8%), 시스틴석 1명(3%) 순이었다. 수술적 요로 결석 제거술은 34명(46%)에서 시행되었으며 자연 배출된 환자는 13명(18%)이었다. 총 6명(8%)에서 요로 결석이 재발하였는데, 척수 수막류로 방광 확장 성형술을 시행 받은 후 신경성 방광을 보이는 환자 4명, 시스틴뇨증 환자 1명, 특별한 유발 인자가 없는 환자 1명으로 구성되었다. 결 론 : 본 연구에서 소아 요로 결석은 요 정체로 요로 감염을 일으킬 수 있는 구조적인 요인이 동반된 경우와 과칼슘뇨증을 포함하는 대사 이상을 보이는 경우가 주된 원인이었다. 따라서 소아 요로 결석 환자에서는 구조적 이상 및 대사 이상에 대한 평가가 반드시 필요하다. 또한 요로 결석의 치료에서는 증상, 결석의 위치, 성분 및 원인을 고려하여 최소한의 침습적인 치료 방법을 선택하여야겠다.
