Most diabetic patients experience diabetic mellitus (DM) urinary bladder dysfunction. A number of studies evaluate bladder smooth muscle contraction in DM. In this study, we evaluated the change of bladder smooth muscle contraction between normal rats and DM rats. Furthermore, we used pharmacological inhibitors to determine the differences in the signaling pathways between normal and DM rats. Rats in the DM group received an intraperitoneal injection of 65 mg/kg streptozotocin and measured blood glucose level after 14 days to confirm DM. Bladder smooth muscle contraction was induced using acetylcholine (ACh, $10^{-4}M$). The materials such as, atropine (a muscarinic receptor antagonist), U73122 (a phospholipase C inhibitor), DPCPX (an adenosine $A_1$ receptor antagonist), udenafil (a PDE5 inhibitor), prazosin (an ${\alpha}_1$-receptor antagonist), papaverine (a smooth muscle relaxant), verapamil (a calcium channel blocker), and chelerythrine (a protein kinase C inhibitor) were pre-treated in bladder smooth muscle. We found that the DM rats had lower bladder smooth muscle contractility than normal rats. When prazosin, udenafil, verapamil, and U73122 were pre-treated, there were significant differences between normal and DM rats. Taken together, it was concluded that the change of intracellular $Ca^{2+}$ release mediated by PLC/IP3 and PDE5 activity were responsible for decreased bladder smooth muscle contractility in DM rats.

Introduction: This study investigated whether renal and bladder ultrasonography (RBUS) findings performed in children with the first incidence of febrile urinary tract infection (UTI) can predict UTI recurrence, high-grade vesicoureteral reflux (high-grade VUR), or acquired renal scarring (aRS). Methods: In all, 917 children who were admitted to our hospital from January 2001 to October 2010, owing to the first incidence of febrile UTI were enrolled in this study. All children underwent RBUS during admission. The mean follow-up was 7.9 months (standard deviation $[SD]{\pm}13.3$). UTI recurrence rates were calculated according to various clinical parameters. By using bivariate and multiple logistic regression analyses, we determined whether age, sex, abnormal RBUS findings, abnormal dimercaptosuccinic acid renal scan findings, or RBUS findings parameters were predictive of UTI recurrence, high-grade VUR, or aRS. Results: On RBUS, hydronephrosis and congenital anomaly of the kidney and urinary tract significantly predicted UTI recurrence. A small kidney, hydroureter, hydronephrosis, cortical thinning, and increased parenchymal echogenicity significantly predicted high-grade VUR. However, their odds ratios (OR) are low compared to normal RBUS findings (recurrent UTI: OR 0.432 and 0.354 vs. 0.934, respectively, high-grade VUR: .019, 0.329, 0.126, 0.058, and 0.188 vs. 2.082, respectively). No RBUS findings significantly predicted aRS. Recurrent UTI, high-grade VUR, and abnormal RBUS findings significantly predicted aRS (OR of 4.80, 4.61, and 2.58, respectively). Conclusion: RBUS is necessary to exclude severe congenital renal scarring, obstructive uropathy, and renal abscess at the first incidence of febrile UTI and is helpful in determining the need for subsequent clinical imaging.

Carcinomas of the stomach can spread to adjacent structure by local extension or metastasize to lymph nodes, peritoneum and distant organs. However, the incidence of metastatic bladder cancer originated at the stomach is very rare. A fifty-five year-old man admitted complaining of epigastric pain for 2 months. A large ulceroinfiltrative lesion was seen in the low body, which was confirmed poorly differentiated adenocarcinoma by histological examination. Abdominopelvic CT scan showed wall thickening at the greater curvature side of gastric body and urinary bladder. Urine cytology was negative. By transurethral resection of bladder, he was diagnosed as metastatic adenocarcinoma of the bladder. We report a case of stomach cancer with metastasis to urinry bladder.

Urodynamics describes a collection of tests designed to evaluate lower urinary tract function and can be performed using retrograde filling of the bladder within a room. In this study, we designed and calibrated the potable urodynamics monitoring system using DSP chip (TMS320VC33, Texas Instrument$^{TM}$, U.S.) and collected pressure and EMG using calibration kit (DPT9022K0122, Medtronics$^{TM}$, U.S.). This system can make patients more comportable and monitor spontaneous urination during daily life.

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.

Objectives: This case report aims to report the clinical effectiveness of the combination treatment of Korean medicine on a post-laparoscopic myomectomy patient's lower urinary symptoms (LUTS). Methods: The patient who diagnosed with uterine myoma had Laparoscopic myomectomy. After the operation, the patient complained of dysuria, nocturia, frequent urination, urgent urination and urinary retention. The patient received combination treatment of Korean medicine during 14 days of hospitalization. The treatment included Ohrim-san, acupuncture, moxibustion, and pharmacoacupuncture. The effects were evaluated through the Numeric Rating Scale (NRS), Overactive Bladder Symptom Score (OABSS), Frequency-Volume chart, and 5-Level version of EuroQol-Five Dimension (EQ-5D-5L). Results: After the treatment, the clinical symptoms such as dysuria, nocturia, frequent urination, urgent urination, urinary retention were improved. Also, the quality of life was enhanced. Conclusions: This case report shows that the combination treatment of Korean Medicine with Ohrim-san may be effective for treating lower urinary tract symptoms (LUTS) after laparoscopic myomectomy.

We report the case of a 14-year-old girl who visited the emergency room because of suprapubic discomfort and sudden acute urinary retention. She did not have any significant medical and surgical history, and her neurological examinations were all normal. Urinary catheterization led to the passage of 500 mL urine. Abdominal ultrasonography showed a hematocolpos that was compressing the urinary bladder. Gynecologic history taking revealed that the patient has not had menarche yet. Therefore, a cruciate incision was performed and her urination became normal. As the surgical outcome after adequate hymenotomy for imperforate hymen is usually good, the diagnosis of imperforate hymen is important. However, this condition is easily missed in the clinic because the first physician visited by the patient rarely takes a detailed gynecologic history or performs appropriate physical examinations. Although rare, imperforate hymen should be considered as a cause of acute urinary retention in the adolescence period. If an adolescent girl presents with abdominal pain and voiding dysfunction, a detailed gynecologic history and appropriate physical examinations of the genital introitus should be performed.

We present a case of a 47-month-old female suffering from acute urinary bladder neck obstruction and bilateral hydronephrosis secondary to a fecaloma. Fecaloma is defined as an accumulation of inspissated feces in the colon or rectum giving the appearance of an abdominal mass. A fecaloma can be developed by diverse causes and the causes of the fecaloma in this case were septum reformation after the Duhamel procedure and long-term constipation. Chronic constipation is very common at outpatient clinic. However, acute urinary retention and voiding difficulty caused by fecaloma in the giant Duhamel pouch has never been reported in Korea. We would like to present our case with acute urinary retention due to a fecaloma and suggest that fecaloma might be considered as one of the causes for acute urinary retention, especially in cases with previous Duhamel operation for repair of Hischsprung disease.

Urinary incontinence is defined as the involuntary and inappropriate loss of urine to failure to emit normal responses as the bladder fills, or inability to reach the bathroom in sufficient time. This study was undertaken to estimate the incidence of urinary incontinence and to determine the correlates of urinary incontinence among women. Subjects of this survey consisted of 408 women, 26 to 83 years old in Incheon. The results of this study are as follows. 1. Of the subjects 50.7% reported urine loss once or twice per year and 28.5% reported incontinence on a regular basis at least once per month. 2. 40.5% of women reported small volume accidents of only 1 to 2 drops, 31.4% ; 1 t-spoon, 16.9% : 1 T-spoon, while 10.1% of women couldn't estimate the volume of urine loss. 3. The volume of urine loss was great enough to require a change of garment (undergarments or outer garments) in 73%. But only 3.8% of those used some type of pads. 4. 56.5% of incontinent women didn't talk about their urinary incontinence with other persons because they felt that urinary incontinence was shameful(38.4%), was not a disease(31.6%), was incurable in spite of treatment(27.4%) and was fearful of being uncured (2.6%). 5. Only 15.5% of urinary incontinent women had sought treatment. 6. The incidence of urinary incontinence was significantly higher in women who had more pariety and uterine-ovarian disease, older age, worrying about where toilets were when they visited new places or voiding anxiety, nocturia and frequency, but was significantly lower in women who had coffee intake. The incidence of urinary incontinence was not related to smoking and enuresis. The results indicate that urinary incontinence is common among young and middle-aged women. That few seek treatment for urinary incontinence suggests a need for more information about women's attitudes toward urinary incontinence and more attention to this problem by health care providers.

Purpose: The aim of this study was to identify volume changes and dose variations of rectum and bladder during radiation therapy in prostate cancer (PC) patients. Materials and Methods: We analyzed 20 patients with PC treated with helical tomotherapy. Daily image guidance was performed. We re-contoured the entire bladder and rectum including its contents as well as the organ walls on megavoltage computed tomography once a week. Dose variations were analyzed by means of Dmedian, Dmean, Dmax, V₁₀ to V₇₅, as well as the organs at risk (OAR) volume. Further, we investigated the correlation between volume changes and changes in Dmean of OAR. Results: During treatment, the rectal volume ranged from 62% to 223% of its initial volume, the bladder volume from 22% to 375%. The average Dmean ranged from 87% to 118% for the rectum and 58% to 160% for the bladder. The Pearson correlation coefficients between volume changes and corresponding changes in Dmean were -0.82 for the bladder and 0.52 for the rectum. The comparison of the dose wall histogram (DWH) and the dose volume histogram (DVH) showed that the DVH underestimates the percentage of the rectal and bladder volume exposed to the high dose region. Conclusion: Relevant variations in the volume of OAR and corresponding dose variations can be observed. For the bladder, an increase in the volume generally leads to lower doses; for the rectum, the correlation is weaker. Having demonstrated remarkable differences in the dose distribution of the DWH and the DVH, the use of DWHs should be considered.
