Modified urodynamics for interstitial cystitis.

Interstitial cystitis (IC) is a poorly understood syndrome. Patients with pelvic pain, urgency, frequency, and/or dysuria may pose a diagnostic dilemma. They may have bladder-related symptoms or they may have nonbladder related symptoms. It is beneficial for the urologist to distinguish between these patients. This study outlined a modified urodynamics test to discriminate between bladder-related and nonbladder-related patients. Consecutive IC patients (bladder-related and nonbladder-related patients) and stress incontinent controls underwent modified urodynamics. Testing consisted of an epithelial leak test, a filling cystometrogram, bladder emptying and instilling lidocaine intravesically, and repeat cystometrogram after bladder emptying. The epithelial leak test and lidocaine test predict reliably if a patient has bladder-related or nonbladder-related symptoms. Modified urodynamics permits a logical stratification of IC patients, and may predict treatment response.

Cystoscopic holmium lithotripsy of large bladder calculi.

Patients with large bladder stones are often difficult to treat endoscopically with the current modalities available to the practicing urologist. We present the results of cystolithotripsy of bladder stones larger than 4 cm with the holmium: Yag (Ho:Yag) laser. In our three patients, all patients were rendered stone free without complication using the Ho:Yag laser, with an average anesthesia time of 50 min. Minimal tissue trauma or stone movement were observed. All stones were easily fragmented, even one stone that had previously been refractory to electrohydraulic lithotripsy. Our conclusion is that the Ho:Yag laser is a safe and effective treatment for patients with large bladder stones. Its use may make it possible to eradicate stones endoscopically that otherwise would require open surgery.
