We investigated whether in human isolated detrusor strips the atropine-resistant contractile response to electrical field stimulation was mediated by ATP (or a related purine), as previously shown in the urinary bladder of other mammalian species. Electrical stimulation (1-50 Hz for 5 s at 1 min intervals, 0.1 ms pulse width, 60 V) elicited reproducible,(More)
1. In strips of human isolated detrusor muscle, the 5-hydroxytryptamine (5-HT) receptor (5-HT4) that mediates facilitation of neuromuscular cholinergic transmission was further characterized by using 5-HT and a series of ligands known for their 5-HT4 agonist (5-methoxytryptamine: 5-MeOT, cisapride, (R,S)-zacopride, BIMU 8) or antagonist (RS 23597, GR(More)
In human isolated detrusor strips, submaximal contractile responses evoked by electrical stimulation were resistant to hexamethonium (30 microM) and abolished by tetrodotoxin (0.6 microM) and hyoscine (1 microM), indicating the activation of postganglionic cholinergic nerves. In methysergide (1 microM) and ondansetron (3 microM) pretreated tissues,(More)
Bladder overactivity (OAB) is a chronic and debilitating lower urinary tract (LUT) disorder that affects millions of individuals worldwide. LUT symptoms associated with OAB, such as urgency and urinary incontinence, cause a hygienic and social concern to patients, but their current pharmacological treatment is largely inadequate due to the lack of(More)
Transurethral incision of the bladder neck (TUIBN) is a simple method of relieving bladder outflow obstruction producing similar results to transurethral resection of the prostate (TURP) when obstruction is caused by small prostate (< 40 gr). The complication rate is low and retrograde ejaculation has a far less degree than after TURP, so less bleeding. The(More)
Urinary incontinence is one of the most frequent diseases in female urology. There are hundreds of therapeutic opportunities without sure outcomes, because of lack of the etiologic cause. Transurethral injection has good results in around of the 60% of the cases with minimal invasivity, good patients compliance, ripetitivity of the method. From 1993 to 1997(More)
The management of the superficial bladder tumor is commonly performed by transurethral resection (TUR) and a following chemotherapy or immunotherapy with exception of Tis. A lot of doubts and questions raise in the management of pT1G3 bladder tumor (BT) for the high grade of recurrencies and progressions. Our experience from 1984 to 1994 about 109 patients(More)
We describe our experience (started in 1988) about the use of urethral stents implanted into patients with prostatic outflow obstruction, unit for prostatic surgery. This technique has been applied successfully with few complications. The use of different stents (Fabian's spiral, mesh stent) allowed us to get the right choices in the different shapes of(More)
In our Department we performed 269 radical cystectomies from January 1985 to April 1996. As regard the urinary diversion 64 patients were undergone to a cutaneous ureterostomy; in 137 we performed a Wallace uretero-intestinal anastomosis; in 6 a Mauclaire rectal diversion; in 12 patients a Mainz Pouch II and 50 selected patients (44 man and 6 ladies) we(More)
