Abstract
PURPOSE We evaluated and identified baseline factors associated with change in health related quality of life among patients with interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome. MATERIALS AND METHODS A total of 191 men and 233 women with interstitial cystitis/bladder pain syndrome or chronic prostatitis/chronic pelvic pain syndrome (collectively referred to as urologic chronic pelvic pain syndrome) were followed for 12 months with bimonthly completion of the Short Form 12 to assess general mental and physical health related quality of life, and with biweekly assessment of condition specific health related quality of life using the Genitourinary Pain Index. A functional clustering algorithm was used to classify participants as improved, stable or worsened for each health related quality of life measure. Ordinal logistic regression was used to determine baseline factors associated with change. RESULTS Physical health related quality of life improved in 22% of the participants, mental health related quality of life improved in 25% and condition specific health related quality of life improved in 47%. Better baseline physical health related quality of life, older age and the presence of nonurological symptoms were associated with lower likelihood of improvement in physical health related quality of life. Better baseline mental health related quality of life, female sex, and greater baseline depression and stress were associated with a lower likelihood of improvement in mental health related quality of life. Better baseline condition specific health related quality of life and more severe baseline urologic chronic pelvic pain syndrome pain symptoms were associated with a lower likelihood of improvement in condition specific health related quality of life. CONCLUSIONS While several nonurologic chronic pelvic pain syndrome factors influenced the trajectory of general health related quality of life over time, only condition specific baseline health related quality of life and urologic chronic pelvic pain syndrome symptoms were associated with urologic chronic pelvic pain syndrome specific health related quality of life change. Significant differences in how urologic chronic pelvic pain syndrome impacts various aspects of health related quality of life suggest a multidisciplinary approach to assessment and treatment of these patients.

Abstract
AIMS To study the impact of glycaemic control on urinary incontinence in women who participated in the Diabetes Control and Complications Trial (DCCT; 1983-1993) and its observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC; 1994-present). METHODS Study participants were women who completed, at both years 10 (2003) and 17 (2010) of the EDIC follow-up, the urological assessment questionnaire (UroEDIC). Urinary incontinence was defined as self-reported involuntary leakage of urine that occurred at least weekly. Incident urinary incontinence was defined as weekly urinary incontinence present at EDIC year 17 but not at EDIC year 10. Multivariable regression models were used to examine the association of incident urinary incontinence with comorbid prevalent conditions and glycaemic control (mean HbA1c over the first 10 years of EDIC). RESULTS A total of 64 (15.3%) women with Type 1 diabetes (mean age 43.6 ± 6.3 years at EDIC year 10) reported incident urinary incontinence at EDIC year 17. When adjusted for clinical covariates (including age, DCCT cohort assignment, DCCT treatment arm, BMI, insulin dosage, parity, hysterectomy, autonomic neuropathy and urinary tract infection in the last year), the mean EDIC HbA1c was associated with increased odds of incident urinary incontinence (odds ratio 1.03, 95% CI 1.01-1.06 per mmol/mol increase; odds ratio 1.41, 95% CI 1.07-1.89 per % HbA1c increase). CONCLUSIONS Incident urinary incontinence was associated with higher HbA1c levels in women with Type 1 diabetes, independent of other recognized risk factors. These results suggest the potential for women to modify their risk of urinary incontinence with improved glycaemic control. (Clinical Trials Registry no: NCT00360815 and NCT00360893).

Abstract
The NIH-Chronic Prostatitis Symptom Index (NIH-CPSI) is a commonly used 13-item questionnaire for the assessment of symptom severity in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). For each item, score ranges are 0–1 (6 items), 0–3 (2 items), 0–5 (3 items), 0–6 (1 item), and 0–10 (1 item). This scoring system is straightforward, but items with wider score ranges are de facto weighted more, which could adversely affect the performance characteristics of the questionnaire. We rescored the NIH-CPSI so that equal weights were assigned to each item, and compared the performance of the standard and rescored questionnaires using the original validation dataset. Both the original and revised versions of the scoring algorithm discriminated similarly among groups of men with chronic prostatitis (n=151), benign prostatic hyperplasia (n=149), and controls (n=134). Internal consistency of the questionnaire was slightly better with the revised scoring, but values with the standard scoring were sufficiently high (Cronbach’s alpha ≥0.80). We conclude that although the rescored NIH-CPSI provides better face validity than the standard scoring algorithm, it requires additional calculation efforts and yields only marginal improvements in performance.

Abstract
PURPOSE We determined the actuarial revision rate for artificial urinary sphincters implanted in patients who were incontinent after radical prostatectomy. MATERIALS AND METHODS We reviewed the records of 70 consecutive patients who were incontinent after radical prostatectomy and who underwent primary artificial urinary sphincter implantation at the University of Michigan between 1984 and 1999. Questionnaires were mailed to all patients with an indwelling device, and telephone calls were placed to those who did not respond to the mailing. Information about surgical revision and current continence status was obtained from chart review and questionnaire response. The Kaplan-Meier curves for actuarial freedom from operative revision were constructed. RESULTS Of the 66 patients with available postoperative data 24 (36%) required reoperation at a mean followup of 41 months. The 5-year actuarial rate for freedom from any operative revision was 50%, and the corresponding rate for cuff revision was 60%. A single operative revision did not predispose the patient to further revision. Questionnaire data indicated a continence rate of 80% (range 0 to 2 pads). CONCLUSIONS Approximately half of the patients who were incontinent after radical prostatectomy may expect to undergo operative revision within 5 years after artificial urinary sphincter implantation. Despite this high reoperation rate, an excellent level of continence is maintained.

Abstract
The budding of the urogenital sinus epithelium into the surrounding mesenchyme signals the onset of prostate morphogenesis. The epithelial and mesenchymal factors that regulate ductal budding and the ensuing process of ductal growth and branching are not fully known. We provide evidence that bone morphogenetic protein 4 (BMP4) is a mesenchymal factor that regulates ductal morphogenesis. The Bmp4 gene was most highly expressed in the male urogenital sinus from embryonic day 14 through birth, a period marked by formation of main prostatic ducts and initiation of ductal branching. From an initial wide distribution throughout the prostatic anlage of the urogenital sinus, Bmp4 expression became progressively restricted to the mesenchyme immediately surrounding the nascent prostatic ducts and branches. Exogenous BMP4 inhibited epithelial cell proliferation and exhibited a dose-dependent inhibition of ductal budding in urogenital sinus tissues cultured in vitro. Adult Bmp4 haploinsufficient mice exhibited an increased number of duct tips in both the ventral prostate and coagulating gland. Taken together, our data indicate that BMP4 is a urogenital sinus mesenchymal factor that restricts prostate ductal budding and branching morphogenesis.

Abstract
OBJECTIVES Pelvic floor tension myalgia may contribute to the symptoms of male patients with chronic pelvic pain syndrome (CPPS). Therefore, measures that diminish pelvic floor muscle spasm may improve these symptoms. Based on this hypothesis, we enrolled 19 patients with CPPS in a 12-week program of biofeedback-directed pelvic floor re-education and bladder training. METHODS Pre-treatment and post-treatment symptom assessments included daily voiding logs, American Urological Association (AUA) symptom score, and 10-point visual analog pain and urgency scores. Pressure-flow studies were obtained before treatment in most patients. Instruction in pelvic floor muscle contraction and relaxation was achieved using a noninvasive form of biofeedback at biweekly sessions. Home exercises were combined with a progressive increase in timed-voiding intervals. RESULTS Mean age of the 19 patients was 36 years (range 18 to 67). Four patients completed less than three treatment sessions, 5 patients completed three to five sessions, and 10 attended all six sessions. Mean follow-up was 5.8 months. Median AUA symptom scores improved from 15.0 to 7.5 (P = 0.001), and median bother scores decreased from 5.0 to 2.0 (P = 0.001). Median pain scores decreased from 5.0 to 1.0 (P = 0.001), and median urgency scores decreased from 5.0 to 2.0 (P = 0.002). Median voiding interval increased from 0.88 hours to 3.0 hours (P = 0.003). Presence of detrusor instability, hypersensitivity to filling, or bladder-sphincter pseudodyssynergia on pretreatment urodynamic studies was not predictive of treatment results. CONCLUSIONS This preliminary study confirms that a formalized program of neuromuscular re-education of the pelvic floor muscles together with interval bladder training can provide significant and durable improvement in objective measures of pain, urgency, and frequency in patients with CPPS.

Abstract
OBJECTIVES To review our experience with the diagnosis and management of genitourinary tract erosions after pubovaginal sling placement. METHODS Clinic and operative records from the urology and gynecology services at two university hospitals were reviewed, and 14 patients were identified who underwent surgical treatment for a urogenital tract erosion after pubovaginal sling placement. The presenting symptoms, physical findings, diagnostic procedures, surgical treatments, and outcomes were reviewed. RESULTS Six vaginal erosions, six urethral and vaginal erosions, and two bladder erosions occurred. All were associated with synthetic sling or suture materials. Common symptoms included vaginal and urethral pain, irritative voiding symptoms, vaginal discharge and/or bleeding, and recurrent urinary tract infections. All vaginal and urethral erosions were detected by physical examination and cystoscopy. Symptoms resolved after removal of the eroded sling component. Of the 12 patients with vaginal or urethral erosions, 7 developed recurrent postoperative stress incontinence. CONCLUSIONS Persistent painful or irritative symptoms after pubovaginal sling placement may be due to urogenital tract erosion, especially if synthetic materials were used. Appropriate evaluation and treatment will result in dramatic symptomatic improvement, although recurrent stress incontinence may occur.

Abstract
PURPOSE The success rate of the bulbourethral sling procedure to treat post-radical prostatectomy incontinence has been reported in a previous chart review analysis. We present further evaluation of the procedure using postoperative mailed questionnaires. MATERIALS AND METHODS Between October 1994 and October 1997, 66 men underwent the bulbourethral sling procedure at our hospital. Postoperatively all patients with indwelling bolsters were mailed questionnaires to assess continence status, discomfort and voiding patterns. RESULTS Of the 66 patients 4 required bolster removal for infection (2), erosion (1) or pain (1), and 1 died. These patients were not assessed further. Questionnaire data were obtained from the remaining 61 patients. At a median followup of 9.6 months (mean 11.9, range 3 to 30) 25 patients (41%) reported complete cure of incontinence, 32 (53%) required no pad for protection and 52 (85%) required 2 pads or less. Persistent perineal numbness or discomfort was present in 32 patients (52%). Of 12 patients who received adjuvant radiation therapy only 1 (8%) was cured. CONCLUSIONS The short-term success rate following the bulbourethral sling procedure is high but persistent perineal discomfort is common. Adjuvant radiation predisposes to treatment failure.

Abstract
PURPOSE The bulbourethral sling procedure is successful in correcting incontinence following radical prostatectomy. However, the mechanism of action of the sling is not intuitively clear. We analyze the results of urodynamic testing on a cohort of men who underwent the bulbourethral sling procedure. MATERIALS AND METHODS Between October 1994 and October 1997, 66 men underwent the bulbourethral sling procedure at our hospital. All but 1 patient underwent preoperative video urodynamic testing. Intraoperative urethral pressure profilometry and abdominal leak point pressure measurements were performed. Additionally, all patients were invited to undergo followup video urodynamic testing. Results were correlated with current continence status. RESULTS Preoperatively all patients demonstrated intrinsic sphincter deficiency. Following sling placement postoperative Valsalva leak point pressure values were significantly increased but maximum resting urethral pressures were unchanged. Preoperative and postoperative Abrams-Griffiths nomograms were not consistent with postoperative bladder outlet obstruction. Postoperative voiding pressures were consistently less than corresponding Valsalva leak point pressures. CONCLUSIONS Patients undergoing video urodynamic testing following the bulbourethral sling procedure demonstrated unobstructed voiding patterns, despite significant increases in Valsalva leak point pressures.

Abstract
PURPOSE We previously reported evidence of hematogenous dissemination of prostate cells during radical retropubic prostatectomy, and we now provide clinical and molecular reverse transcriptase-polymerase chain reaction (RT-PCR) followup of that patient cohort. MATERIALS AND METHODS A total of 101 men with clinically localized prostate cancer were prospectively enrolled in the study. The prostate specific antigen (PSA) RT-PCR assay was performed on peripheral venous blood samples preoperatively in 101, during surgery in 29, during and up to 12 weeks after surgery in 50 and at least 1 year postoperatively in 65 patients. Correlation with clinical (PSA) indicators of recurrence was performed. RESULTS Of the 101 patients 9 demonstrated biochemical evidence of prostate cancer progression (median followup 22 months). Of the 50 men with perioperative molecular results the RT-PCR positive rate increased from 22% preoperatively in 11 to 48% in 24 (p = 0.02) and then decreased to 10% in 4 of 40 men at 1 year postoperatively (p = 0.07). Molecular followup at a minimum of 1 year after radical retropubic prostatectomy was obtained in 65 men, of whom the RT-PCR positive rate decreased from 23% preoperatively in 14 to 9.2% in 6 (p = 0.05). No significant correlation was observed between a persistently positive RT-PCR result and biochemical failure. CONCLUSIONS Although a significant proportion of men have molecular evidence of hematogenous prostate cell dissemination intraoperatively, longitudinal molecular and clinical followup demonstrates reconversion to a negative status as the predominant trend. At relatively short followup no significant correlation was identified between the RT-PCR result and the PSA progression-free survival.

Abstract
The role of Hoxa-13 in postnatal morphogenesis of the male accessory sex organs was assessed by correlating the Hoxa-13 expression domain with phenotypic abnormalities in heterozygous Hypodactyly mutants. Hypodactyly is a naturally occurring semi-dominant mutation that results from a 50-base pair deletion in exon one of the Hoxa-13 allele. We demonstrate that Hoxa-13 is broadly expressed in the developing lower genitourinary tract and that the Hypodactyly mutation results in a specific phenotype characterized by decreased size and branching of the dorsolateral and ventral prostate and abnormal seminal vesicle morphology. This phenotype partially overlaps the genitourinary phenotype observed in Hoxd-13 deficient mice and comparison showed similar domains of Hoxa-13 and Hoxd-13 expression in the lower genitourinary tract. The similarity in expression and overlap in phenotype resulting from mutation is consistent with additive function and partial functional redundancy of Hoxa-13 and Hoxd-13 in male accessory sex organ development.

Abstract
The prostate gland develops from the urogenital sinus by a testosterone-dependent process of ductal morphogenesis. Sonic hedgehog (Shh) is expressed in the urogenital sinus epithelium and the time course of expression coincides with the formation of the main prostatic ducts. Expression is most abundant in the lumen of the urogenital sinus and in the contiguous proximal duct segments. The initial upregulation of Shh expression in the male urogenital sinus depends on the presence of testosterone. The function of Shh was examined in the male urogenital sinus which was transplanted under the renal capsule of an adult male host mouse. Blockade of Shh function by a neutralizing antibody interferes with Shh signaling and abrogates growth and ductal morphogenesis in the transplanted tissue. These observations show that testosterone-dependent Shh expression in the urogenital sinus is necessary for the initiation of prostate development.

Abstract
The role of mammalian Hox genes in regulating segmental patterning of axial structures and the limb is well established. A similar role in development of soft tissue organ systems has recently been suggested by observations linking several 5' members of the HoxA and HoxD clusters to segmentation events and morphogenesis in the gastrointestinal and genitourinary systems. We have specifically examined the role of Hoxa-10 in development of the male accessory sex organs by characterizing expression of Hoxa-10 in the developing male reproductive tract and correlating expression to morphologic abnormalities in knockout mice deficient for Hoxa-10 function. We report that Hoxa-10 expression in the Wolffian duct and urogenital sinus is regionally restricted and temporally regulated. The domain of expression is defined anteriorly by the caudal epididymis and extends posteriorly to the prostatic anlagen of the urogenital sinus. Expression was maximal at E18 and down-regulated postnatally, well before accessory sex organ morphogenesis is completed. Expression in the prostatic anlagen of the urogenital sinus cultured in vitro does not depend upon the presence of testosterone. Loss of Hoxa-10 function is associated with diminished stromal clefting of the seminal vesicles and decreased size and branching of the coagulating gland. The ductal architecture of the coagulating gland was altered in approximately 30% of mutants examined and suggests a partial posterior morphologic transformation of the coagulating gland. We interpret these data to indicate that Hoxa-10 is expressed in a region specific manner during late gestation and into the perinatal period and that Hoxa-10 is required for normal accessory sex organ development.

Abstract
PURPOSE We performed followup of a cohort of women who underwent the Stamey endoscopic needle suspension (group 1) or the Marshall-Marchetti-Krantz vesicourethropexy (group 2) between 1975 and 1983. MATERIALS AND METHODS Telephone interviews were performed to assess current continence status and time to failure. Risk factors for recurrence of incontinence were correlated with long-term results. RESULTS Long-term data were obtained for 32 of 41 women (78%) in group 1 and 36 of 54 (67%) in group 2. Range of followup was 9.4 to 19.9 years (median 15.0, mean 15.2) in group 1 and 13.2 to 21.9 (median 16.8, mean 17.0) in group 2. Of group 1 patients 44% remained dry compared to 33% of group 2 patients. Persistent local side effects were reported by 9% of group 1 and 0% of group 2. Urinary urgency was present in 70% of group 1 patients and 23% of group 2. There was no relationship between long-term operative success and age at surgery, degree of preoperative incontinence, parity, obesity, prior incontinence surgery or prior hysterectomy for either procedure. CONCLUSIONS The Stamey and the Marshall-Marchetti-Krantz procedures yield high initial cure rates with progressive, parallel declines in continence status with time.

Abstract
PURPOSE We evaluate the efficacy of the male bulbourethral sling procedure in the treatment of post-radical prostatectomy urinary incontinence. MATERIALS AND METHODS We reviewed the records of 64 consecutive men with severe post-prostatectomy incontinence who underwent the male bulbourethral sling procedure at Northwestern Memorial Hospital and Stanford University Hospital. Preoperatively 50% of the patients were completely incontinent (diapers, clamps or condom catheter), and the remainder required a mean of 4.7 pads per day. Data were collected by chart review, patient interviews at followup appointments and telephone interviews. Median followup was 18.1 months (mean 22.4, range 6.5 to 53.8). RESULTS Following a single sling procedure 36 patients (56%) became dry, and 5 (8%) were significantly improved. In 17 patients 23 retightening procedures were performed, which decreased the median followup to 16 months and increased the success rate to 75% (67% cured, 8% improved). The revision, erosion and infection rates were 27, 6 and 3%, respectively. CONCLUSIONS The male bulbourethral sling procedure is effective treatment for post-radical prostatectomy urinary incontinence. Patients who had received adjuvant radiation therapy demonstrated a lower continence rate than those who had not. Further followup is needed to assess long-term efficacy.

Abstract
Image analysis provides a powerful tool for quantifying cell motility and has been used to correlate motility with metastatic potential in an animal model of prostate cancer. However, widespread use of this image analysis method has been limited because earlier methods of quantitative analysis required time-intensive and subjective manual tracing of cell contours. In this report, we describe a fully automated image segmentation algorithm for detection and morphometric description of prostatic cells. The segmentation system was tested on prostate cell images generated from Hoffman modulation contrast microscopy (47 cells at 64 time points = 3,008 images) and differential interference contrast microscopy (29 cells at 64 times points plus 1 cell at 62 time points = 1,918 images). Morphometric measurements were derived from computer-determined cell boundaries and compared with the same measurements derived from manually traced cell boundaries. Final correlation coefficients for area and perimeter measurements for Hoffman and differential interference contrast microscopy were (0.76, 0.62) and (0.93, 0.93), respectively. Results with our differential interference contrast images demonstrate that our segmentation algorithm reliably and efficiently replaces the need for manually traced cell boundaries in addition to eliminating intraobserver variation. Our automated segmentation process will have immediate utility in our motility analysis system that relates cell motility with metastatic potential of prostate cancer.

Abstract
OBJECTIVE Serum prostate-specific antigen (PSA) values are most useful for prediction of disease recurrence after surgery. It is unknown whether a detectable PSA level after surgery indicates a local recurrence potentially benefiting from pelvic irradiation or distant metastases requiring hormonal treatment. METHODS We analyzed postoperative rate of change of serum PSA levels as a predictor of local versus distant disease recurrence after radical prostatectomy. Between 1982 and 1991, 1,058 men underwent radical prostatectomy for localized prostate cancer and follow-up consisted of determining serum PSA levels and digital rectal examinations. Clinical follow-up of 542 men for four or more years and 78 men for eight or more years yielded ten-year actuarial disease recurrence rates of 4 percent for local recurrence, 8 percent for distant metastases, and 23 percent for an isolated elevation of serum PSA level only. Fifty-one patients with isolated elevations of PSA levels only were followed expectantly until they were diagnosed with either local or distant metastases. RESULTS A linear mixed effects regression analysis was used to model these data. Using these models, the time to a serum PSA level of 0.5 ng/mL, the PSA level one year following surgery, pathologic stage, Gleason sum, and the rate of change of PSA (PSA velocity [PSAV]) were tested as predictors of local versus distant metastases. A combination of PSAV, pathologic stage, and Gleason grade best distinguished local from distant metastases. CONCLUSIONS These data suggest that PSAV in men with an isolated elevation of PSA levels following radical prostatectomy might aid in clinical decision making.

Abstract
1. With an average follow-up of 53 months (range 12-120 months), 19.4% (185/955) of men have had a cancer recurrence after radical prostatectomy for clinically localized prostate cancer. A detectable serum PSA was the only evidence of recurrence in 11.2%, whereas 2.2% have had a recurrence locally and 6% with distant metastases. 2. The actuarial status at 10 years was 70% for undetectable serum PSA; 23% for isolated serum PSA elevation only; 7% for distant metastases; and 4% for local recurrence. 3. In our study, no patient demonstrated disease progression (local or distant) without detectable serum PSA. 4. The actuarial likelihood of an elevated serum PSA increased with increasing clinical stage, Gleason score, preoperative serum PSA concentration, and pathologic stage. 5. The actuarial recurrence rate for tumors with a Gleason score of 7 was not statistically different from the recurrence rate for lesions of Gleason score 8-10. 6. There exist marked differences in actuarial recurrence-free probabilities for men with tumors of low Gleason score (< 7) compared with those with tumors of high Gleason score (> or = 7) when there is pathologically established capsular penetration. 7. Patients with preoperative serum PSA concentrations greater than 10.0 ng/mL are at a statistically increased risk of recurrence. 8. Men who have detectable serum PSA within the first year after surgery are at a significantly higher risk of disease progression than those men who have measurable serum PSA in postoperative years two and three. 9. Men with an isolated elevation of serum PSA after radical prostatectomy have a 25% likelihood of harboring an occult local recurrence. However, radiation therapy produces a sustained suppression of PSA to undetectable levels for 2 years or more in only 10% of men. This suggests that radiation therapy is not effective in sterilizing occult local residual tumor in many men. 10. Valuable information concerning disease recurrence and progression can be obtained through early postoperative measurement of serum PSA. This article demonstrates the long-term value of serum PSA as a measure of progression after anatomic radical prostatectomy.
