Our focus is to obtain expert knowledge in the incidence and prevalence of bladder cancer in specific patient populations and implement screening tests to evaluate the predictive value of these tests. Review of efficacy and long-term compliance of multiple treatments (intracavernous injections, vacuum constriction devices, MUSE- transurethral insertion of alprostatdil and sildenafil citrate) used to treat erectile dysfunction following radical surgeries.
Our Center is among the first to conduct novel study to address sexual dysfunction in subset of patients (both male and female) undergoing radical cystectomy. Our ongoing studies are focused on cutting edge issues in the management of erectile dysfunction. We are interested in investigating the potential use of vascular endothelial growth factor gene therapy to stimulate cavernous nerve regeneration after nerve sparing and non-nerve sparing radical prostatectomy and enhance the return of natural erections sufficient for sexual intercourse. To continue our ongoing research on assessment of sexual dysfunction in male and females patients who have undergone radical cystectomy. To assess erectile function after I-125 seed radiation therapy for prostate cancer (T1-2) and the role of sildenafil citrate. Our research interests in bladder cancer are comprehensive, from screening and early detection to monitoring the treatment response of bladder cancer to BCG, to nerve sparing radical cystectomy, and to continent diversion for invasive and metastatic disease.
Our basic science research includes studies on the immunologic response to BCG and whether this response can be augmented with various interferons. We are studying the ability of targeted multicolor fluorescence in situ hybridization (FISH) to identify malignant cells in cytological equivocal cases where morphology alone does not allow definitive diagnosis. We are conducting an open comparative within patient controlled phase 3 multicenter Study of Hexvix fluorescence cystoscopy and standard cystoscopy in the detection of carcinoma in situ in patients with bladder cancer. Our focus is to expand on this solid foundation and to obtain expert knowledge in the incidence and prevalence of bladder cancer in specific populations and implement screening tests, evaluate the predictive values of these tests, and determine the diagnostic algorithm for early detection of bladder cancer. The research laboratory is interested in the treatment of localized prostate cancer with radical prostatectomy and the associated complications of incontinence and erectile dysfunction (ED).
Our clinical research includes the treatment of localized prostate cancer with radical prostatectomy, the associated complications of incontinence and ED, and quality of life issues in urological practice.
Erectile dysfunction is an important morbidity factor after the treatment of localized prostate cancer.
Our ongoing study is focused on assessing long-term potency following I-125 seed implantation and efficacy of sildenafil citrate in management of ED following I-125 seed implantation. Radical cystectomy is the treatment of choice for locally advanced but invasive cancer of the bladder. Early use of vacuum constriction device (VCD) following radical prostatectomy (RP) facilitates early sexual activity and potentially earlier return of erectile function.
Role of sildenafil citrate in the management of erectile dysfunction following I-125 seed insertion for localized prostate cancer.
Role of sildenafil citrate in management of sexual dysfunction following radical cystectomy. NEUROTOXICITY can cause irreversible nervous system damage related to cell death or permanent alterations of cell structure and receptor sensitivity.
IT HAS BEEN KNOWN FOR SOME TIME that mental health professionals are not immune from physical and psychological trauma and its potential sequelae (Jayaratne, Vinokur-Kaplan, Nagda. Objective: A report of a case of a low-tech non-dynamometric functional exercise program in the rehabilitation of a functionally unstable lower back, associated with failed back surgery.
Male sexual dysfunction after fracture of the pelvis is more common than previously supposed with rates as high as 30% reported when the complaint is specifically sought.
Erectile dysfunction has been defined as the inability to achieve or maintain an erection adequate for sexual satisfaction. Few studies have reported the overall incidence of sexual dysfunction after fractures of the pelvis, most concentrating on patients with urethral injury. A strong association between urethral disruption and subsequent impotence is well documented. Erectile dysfunction after injury to the pelvis is due to a combination of neurogenic, vascular, corporal and psychogenic injury.9,13-16 Table II summarises the information available in the literature on the pathogenesis of impotence in these patients.
Levine et al14 investigated impotent patients, who had suffered blunt perineal or pelvic trauma, using selective internal pudendal arteriography. Munarriz et al24 investigated a similar group of patients, 42 of whom had suffered fractures of the pelvis.

Our recent study is focused on early treatment program following radical prostatectomy, a strategy used to help promote early nerve recovery and regeneration following radical surgery. We reported sexual function data in a contemporary radical cystectomy series by using the SHIM (IIEF-5) for males and a modified IFSF for females.
Our laboratory has been at the forefront of clinical research in the area of urinary tumor markers and their role in screening or early detection of bladder cancer. This database identifies patients who have been screened for bladder cancer, have been treated with intravesical chemotherapy, and have undergone radical surgery with continent diversion.
In future, we would like to examine the relationship between levels of reactive oxygen species and the progression of superficial bladder cancer after intravesical therapy. Hexvix contains hexyl-5-aminolevulinate which are precursors of photoactive porphyrins preferentially taken up by bladder cancer cells, which can be utilized for identification and treatment guidance of malignant and pre-malignant lesions.
Our interests in this field have been on surgical margin status and the effect of nerve-sparing surgery on incontinence and erectile function. Our research also involves a review of efficacy and long-term compliance of multiple treatments (intracavernous injections, vacuum constriction devices, MUSE- transurethral insertion of alprostatdil and sildenafil citrate) used to treat ED following radical surgeries.
In the past, the majority of the patients were elderly, where post-radiation potency was not a major factor in their decision to undergo radiation.
This study will evaluate the drug's long-term effects after brachytherapy for treatment of localized prostate cancer. Outcome data following radical cystectomy with or without orthotopic diversion has focused primarily on cure, urethral recurrence, and continence.
To this inarguable truism, I would add that there's an equally thin line between clever and clever dick. With the increase in survival from major injuries, the long-term consequences of trauma are being seen with increasing frequency. In 3% of patients with sexual dysfunction, this will be secondary to an episode of pelvic or perineal trauma.8 In younger impotent patients, often at the beginning of their sexual lives, the motivation to restore function is very high. King,9 in a review of 90 patients published in 1975, found an incidence of 5% of dysfunction in patients without urethral injury, rising to 42% when urethral injury had occurred. The prostatic urethra is particularly vulnerable to shearing forces, being fixed by the urogenital diaphragm and puboprostatic ligaments to the ischiopubic rami and the symphysis pubis.1,3,12 Upward or posterior displacement of the symphysis will therefore subject the fixed urethra to considerable stress. Severe neurological injury, particularly involving the lumbosacral plexus, may occur at the time of the initial injury and during subsequent operations. All those with fractures, and 96% overall, had an abnormality of the cavernosal response to pharmacological stimulation, suggesting that there was a haemodynamic component to their pathology; 80% of patients who had sustained trauma to the pelvis had an abnormality of venous outflow and 70% an abnormality of venous occlusion. While the penis itself is free and therefore relatively protected from the effect of blunt trauma, the corpora are attached to the undersurface of the ischiopubic rami. The laboratory is interested in comparing the efficacy and durability of various types of continent reservoirs. We are involved in studies to assess the results of sildenafil citrate in salvaging erectile function in postprostatectomy patients.

In future we are interested in investigating the potential use of vascular endothelial growth factor gene therapy to stimulate cavernous nerve regeneration after nerve sparing and non-nerve sparing radical prostatectomy and enhance the return of natural erections sufficient for sexual intercourse. A larger percentage of younger patients are choosing radiation therapy in recent years and therefore, the issue of post-radiation potency is becoming a major concern.
We were among the first to conduct this novel study to address sexual dysfunction in subset of patient's (male & female) undergoing radical cystectomy. This review addresses the current understanding of the incidence, mechanism of injury, pathophysiology, acute management, subsequent investigation and long-term treatment of erectile dysfunction after injury to the pelvis.
Machtens et al,10 in 2001 described an overall incidence of 11.6% in men in a series of 1722 patients who had suffered fractures of the pelvis.
The quoted incidence varies widely from less than 1% to more than 30%.16-20 Majeed18 found clinical evidence of neurological injury, confirmed by EMG studies, in 33% of patients with unstable fractures of the pelvis, but only 16% were identified on admission.
The vessels may be lacerated directly or by damage to the intima leading to thrombosis.21 Sharlip22 described obliteration of both the internal pudendal arteries at the level of the urogenital diaphragm on arteriography in three patients.


All the patients with fractures who underwent cavernosography had abnormal findings, 97% of these being proximal, site-specific leaks into local venous structures. We were among the first to investigate the effects of this new oral medication in patients following radical prostatectomy and to study the impact of the presence or absence of the neurovascular bundles.
Using a SHIM (IIEF-5) validated questionnaire for males and a modified IFSF for females, we are assessing sexual function data in a contemporary radical cystectomy series. Although this is the largest number reviewed to date, the methods used for assessment were not stated.
All patients showed at least partial recovery by three to 12 months, continuing for up to 24 months.
They remained impotent despite formation of collateral vessels and retrograde filling of the dorsal and deep penile arteries. Lesions of the pudendal or common penile arteries were seen in 90% of those with a fracture as opposed to 35% of those without.
Leaks were seen at three or more sites in 60%, the most common being the crural and cavernous veins and the proximal corpus spongiosum. Such injury could induce fibrosis during healing, subsequently impairing the ability to dilate.8 MRI has shown a high incidence of injury to the corpora in patients with a fracture, urethral injury and impotence. We have recently assessed long-term follow-up compliance with sildenafil citrate therapy following radical prostatectomy.
We are stratifying the sexual response as per orthotopic diversion to assess the efficacy of sildenafil citrate (in male) for salvaging ED following radical cystectomy.
Malavaud et al11 used a previously validated scale to assess erectile dysfunction in 46 patients who had recovered from pelvic fractures. However, 48% of the latter group were more likely to have had an isolated lesion in the cavernous artery compared with only 8% in the group with a fracture.
This venous abnormality was more common than in the patients who had not suffered a fracture.
Armenakas et al26 demonstrated injuries in 12 of 15 patients examined, including eight avulsions and four fractures. Their patients reported significantly lower scores in sexual satisfaction than normal historical controls, although the latter group was of a higher mean age by 20 years. The efferent nerve fibres supplying the cavernous bodies lie within the cavernous nerves to the urethra and symphysis pubis can be injured in isolation without other obvious neurological impairment as they leave the bony pelvis.
Similar lesions were observed in a control group with vasculogenic impotence but with no history of trauma, although proximal lesions were more common. Angiography again detected widespread lesions, most frequently in the common penile and cavernous arteries. Doppler imaging revealed that 12 patients had primarily vasculogenic impotence with low peak flow velocities, and three had neurogenic impotence. They concluded that the most likely cause of the widespread venous leak was the direct impact of the fixed proximal corpora against the pubic rami or a shearing effect at the point of fixation. Of the vasculogenic group, five had a significant venous leak as shown by large rates of diastolic flow. The only characteristic of the fracture which correlated positively with impaired sexual potency was diastasis of the symphysis pubis.
These were associated with severe injury to the corpora in four patients and it may be that fibrosis may also interfere with the complex veno-occlusive mechanisms.26 Such injuries may lead to the formation of venous fistulae, allowing abnormal leakage of blood. A trend towards impairment after urethral injury was also observed, although this did not reach statistical significance. This suggests that, taking the data as a whole, impotence is seen in about 42% of patients who have a urethral injury. The overall rate of dysfunction after fracture is likely to be higher than the historical figure of 5%,9 lying somewhere between 11%10 and 30%11 depending upon how dysfunction is assessed.
