Interstitial cystitis (IC) has been described as a chronic debilitating sterile inflammatory multifactorial bladder syndrome of unknown etiology. IC is characterized by bladder pain (or suprapubic pain) associated with urgency, urinary frequency, and nocturia. Because the pathogenesis of IC remains unclear, it is still an enigma and represents a diagnostic and therapeutic challenge. The diagnosis of IC remains unclear and is based on exclusion of other diseases. Consequently, IC has usually been underdiagnosed, and the consensus on best available treatment for the disease is lacking. The current goal for the treatment of IC is usually symptomatic relief, and treatment protocols are based on empiricism. Multiple forms of therapy are available, and most patients can be managed conservatively. Nevertheless, the efficacy of most treatments is short term. This review article gives an overview of the available treatments for IC.

Objective: To assess the efficacy of hydrodistention (HD) followed by bladder training (BT) versus HD alone in patients with interstitial cystitis (IC). Methods: A total of 70 patients with IC were included and randomly assigned to two groups: one treated with HD (HD group) and the other treated with HD plus BT (HD plus BT group). Each patient was followed up using a weekly diary for 8 weeks after HD and monthly thereafter for 6 months after HD. Evaluation parameters included age, duration of IC in years, how many doctors visited before treatment, urgency, bladder pain, daytime voided volume per void, nocturnal volume per void, daytime voids per day, and nocturia per day. Results: Age, duration of IC in years, doctors visited before treatment, and voiding profiles of patients before treatments between the two groups did not show statistical significance. However, at 24 weeks after HD, the proportions of urgency, and bladder pain of the HD group versus the HD plus BT group were 43.48% versus 10.71% (p = 0.008), and 34.78% versus 14.29% (p = 0.086), respectively. Concurrently, the mean ± standard deviation of daytime voided volume per void, nocturnal volume per void, daytime voids per day, and nocturia per day of the HD group and HD plus BT group are 212.2 ± 114.2 mL and 300.1 ± 90.2 mL (p = 0.005), 276.8 ± 113.0 mL and 360.0 ± 129.6 mL (p = 0.018), 8.2 ± 3.2 and 6.2 ± 1.4 (p = 0.010), and 2.2 ± 1.2 and 1.5 ± 0.7 (p = 0.019), respectively. Conclusion: HD followed by BT produced a statistically significantly better effect than HD alone in the treatment of patients with IC.

Objective: To investigate whether the O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI) is efficacy measure tool for interstitial Cystitis (IC) treatment with hydrodistention (HD) and bladder training (BT)., Materials and Methods: From January 2003 to March 2006, 108 consecutive IC patients were treated by HD and BT after HD. This study evaluated the efficacy of treatment with the specific questionnaire for IC, the ICSI and ICPI. Each patient filled out the questionnaire before HD and three months after HD and BT. The efficacy of the treatment was evaluated using the average scores of ICSI and ICPI., Results: The mean ± margin of error, (95% confidence interval) of total scores of ICSI and ICPI were 13.89 ± 2.95, (13.33-14.45) and 12.51 ± 2.50, (12.04-12.98) before HD, respectively, and were 2.70 ± 1.16, (2.44-2.95) and 1.99 ± 1.27, (1.71-2.26) (all p < 0.005) three months after HD and BT, respectively., Conclusion: O'Leary-Sant ICSI and ICPI is not only a screening tool for IC but also a useful assessment tool for IC treatment outcomes., (Copyright © 2018.

Introduction/objective: The dynamic hydrodistention (HD) classification is a basic and objective way of rating the ureteral orifice opening. This study evaluated the value of hydrodistention of the ureteral orifice in the diagnosis of vesicoureteral reflux (VUR)., Material and Methods: Between January 2012 and March 2013 the HD grade in 106 ureters was prospectively assigned. A 9.5-Fr rigid cystoscope with a 0-degree lens was used in all procedures. Warm saline was used and the irrigation bag was placed approximately 1 m above the bladder level on full flow. The grading is as follows: H0 denotes absence of ureteral dilation; H1 indicates dilation of the ureteral orifice only; H2 allows visualization of the intramural ureter; and H3 allows visualization of the extramural ureter. Indications for cystoscopy were endoscopic and open surgical treatment of VUR, stent removal, and any other diagnostic reasons. Exclusion criteria were patients with: infravesical obstruction, neuropathic bladder, severe detrusor over activity/dysfunctional voiding, duplex system, paraureteral diverticulum, bladder exstrophy and grade-1 VUR. The 51 refluxing ureters (RUs) were compared with 55 non-refluxing ureters (NRUs). Finally, sensitivity, specificity, positive and negative predictive values, and accuracy rate of HD were evaluated., Results: A total of 106 ureters in 61 patients with a mean age of 5.3 ± 3.9 years (range 2 months-15 years, median 5 years) were prospectively assigned. The mean HD grade in the RUs was 2.17 ± 0.55. The mean HD grades were 2.0 ± 0.63, 2.07 ± 0.53, 2.38 ± 0.5 and 2.5 ± 0.57 for VUR grades 2-5, respectively. The mean HD grade in the NRUs was 1.60 ± 0.70. The HD grades were H0 to H3 in 7.3%, 30.9%, 56.4% and 5.4% of the NRUs, respectively. The RUs group (2.17 ± 0.55) showed a statistically higher HD grade than the NRUs group (1.60 ± 0.70) (P < 0.005). Sensitivity, specificity, positive and negative predictive values, and accuracy rate of HD grading in the diagnosis of VUR were 92%, 38%, 58%, 84%, and 64%, respectively. The mean HD grade in contralateral ureters of unilateral VUR was 1.55 ± 0.72 and HD grades were H0-H3 in 0%, 55.6%, 33.3% and 11.1% of these nine ureters, respectively. In these nine non-refluxing contralateral ureters, after endoscopic correction of ipsilateral VUR, new contralateral VUR did not occur., Conclusion: Even though HD grade was high in the VUR group and popularity of the HD grading is on the increase, HD grading by itself still has a low diagnostic value., (Copyright © 2015 Journal of Pediatric Urology Company.
