PURPOSE Clinicians have long been hampered by the inability to distinguish patients with localized prostate cancer who will and will not respond to radiotherapy. In a significant proportion of patients therapy fails as determined by increasing posttreatment serum prostate specific antigen (PSA). We evaluated the expression of 2 key regulators of apoptosis,(More)
OBJECTIVE To determine the prevalence of interstitial cystitis and endometriosis in patients with chronic pelvic pain. METHODS A prospective analysis was conducted in 178 women with CPP who presented with bladder base/anterior vaginal wall and/or uterine tenderness, with or without irritative voiding symptoms. The Potassium Sensitivity Test was used to(More)
OBJECTIVE To compare the efficacy and safety of the tension-free vaginal tape (TVT) and laparoscopic Burch procedures in treating genuine stress urinary incontinence in obese patients. METHODS This was a retrospective evaluation of 91 consecutive cases of TVT alone or TVT combined with other procedures from April 1999 through March 2000 and 51 consecutive(More)
Laparoscopy using miniature (2-3.5 mm) instruments was introduced in the late 1980s and early 1990s. Though mini laparoscopy (Mini) created new opportunities for surgical diagnosis and therapy, the limitations of early instruments inhibited widespread adoption. This is no longer the case. Mini is enjoying a renaissance, due to several factors: the(More)
PURPOSE To examine the effect of retinoic acid on prostate ductal morphogenesis. MATERIALS AND METHODS Newborn male Balb/C mice were injected with 25 mg./kg. all-trans retinoic acid or vehicle alone. Animals were sacrificed at 60 days of age and prostate ductal morphology was quantitatively assessed by microdissection. Total prostate DNA was quantitated(More)
OBJECTIVE We evaluated the prevalence of positive potassium sensitivity and cystoscopy with hydrodistention findings in patients with overactive bladder. METHOD This was a prospective cohort study of 98 patients who presented with overactive bladder symptoms. The diagnosis of overactive bladder is established by the presence of irritable voiding symptoms.(More)
I faced such challenges when I began my practice 20 years ago in Lima, Ohio. In the early 1990s, I began diagnosing women who came to me complaining of pelvic pain with endometriosis and, with the techniques I learned from Drs. Camran Nezhat, Farr Nezhat, Harry Reich, and Charles Koh, I treated these women by using laparoscopic laser ablation of the(More)
OBJECTIVE To determine the value in the initial laparoscopic and cystoscopic evaluation of avoiding the unnecessary delay in diagnosing the "evil twins" of chronic pelvic pain syndrome, endometriosis and interstitial cystitis. METHODS We performed a retrospective review of 60 women ranging in age from 19 to 62. They underwent concurrent laparoscopy,(More)
OBJECTIVES Hysterectomies may be performed unnecessarily in women with chronic pelvic pain if the diagnosis of interstitial cystitis is not considered. The objectives of this study were to investigate the prevalence of interstitial cystitis in patients with posthysterectomy chronic pelvic pain and to evaluate the efficacy of various therapies for(More)
BACKGROUND Interstitial cystitis is a clinical syndrome characterized by symptoms of pelvic pain, urinary urgency and frequency, and nocturia. It can be difficult to accurately identify interstitial cystitis because the symptoms overlap many other common gynecologic and urologic conditions. Patients with undiagnosed interstitial cystitis may undergo(More)
