Abstract
BACKGROUND: In patients with non-invasive urothelial carcinoma of the prostatic urethra (PUC), treatment with Bacillus Calmette-Guérin (BCG) could be beneficial. OBJECTIVE: To assess the response rates to BCG in the different tumor stages, to describe the clinical impact of transurethral resection of the prostate (TURP) before BCG treatment, and to review the side effects of BCG treatment for PUC. METHODS: A systematic search was conducted using the PubMed database to identify original studies between 1977 and 2019 reporting on PUC and BCG. RESULTS: Of a total of 865 studies, ten were considered for evidence synthesis. An indication for BCG treatment was found in non-stromal invasive stages (Tis pu, Tis pd) and in stromal infiltrating cases (T1) of primary and secondary PUC when transitional cell carcinoma was the histology of origin. Studies including patients treated with TURP before BCG showed a better local response in the prostatic urethra with a higher disease free survival (DFS) (80–100% vs. 63–89%) and progression free survival (PFS) (90–100% vs. 75–94%) than patients in studies in which no TURP was performed. However, this difference in recurrence and progression in the prostate neither affected the total PFS (57–75% vs. 58–93%), nor the disease specific survival (70–100% vs. 66–100%). CONCLUSIONS: The use of resection loop biopsies of the prostatic urethra in appropriate cases during the primary work-up for suspected PUC, as well as the use of the current TNM classification for PUC, need to be improved. BCG therapy for non-stromal invasive stages of PUC show a good local response. Local response is further improved by a TURP before BCG therapy, although the overall prognosis does not seem to be affected. Further evidence for BCG treatment in the rare cases of stromal invasive PUC is needed. Specific side effects of BCG treatment for PUC are not reported.

Surgical challenges and considerations in Tri-modal therapy for muscle invasive bladder cancer. Urol Oncol 2021; 40:442-450. [PMID: 33642229 DOI: 10.1016/j.urolonc.2021.01.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Revised: 12/13/2020] [Accepted: 01/08/2021] [Indexed: 01/20/2023]
Abstract
Trimodal therapy (TMT) for muscle invasive bladder cancer has become an accepted alternative to radical cystectomy and has become integrated into national guidelines as standard a treatment option. The urologist plays a critical role in proper patient selection, thorough transurethral resection, ongoing cystoscopic surveillance and management of local recurrences. There exists multiple patient related and tumor related factors, which contribute to the selection of TMT vs. radical cystectomy for a patient with muscle invasive bladder cancer. Although the ideal patient for TMT has a tumor which can undergo a visibly complete resection, has no associated hydronephrosis, does not invade the prostatic urethra and is not associated with diffuse carcinoma in situ throughout the bladder, select patients who do not meet all these criteria can still be successfully treated with this approach. A multidisciplinary approach including urology, radiation oncology and medical oncology is paramount with clear communication of tumor location, timing of chemoradiation and repeat cystoscopic resection followed by surveillance. Nonmuscle invasive bladder cancer recurrences can occur in up to 26% of patients after completion of TMT, with many being treated by routine and standard therapy for non-muscle invasive bladder cancer. However, in this population after TMT, early salvage cystectomy should be considered in those with adverse features, including T1 disease, tumor greater than 3 cm, CIS, or lymphovascular invasion. Salvage cystectomy can be performed for local recurrences with acceptable oncologic control and no clear evidence of any greater risk of early complications; however, there may be a slightly increased risk for late complications, namely small bowel obstruction, ureteral stricture, and parastomal hernia. An understanding of these surgical considerations is of utmost importance to the treating urologist in selecting and managing a patient through TMT.

Abstract
Introduction and Objectives A comparative study of standard radical cystectomy and prostate capsule sparing radical cystectomy regarding functional and oncological outcomes. Materials and Methods A randomized study of 96 patients with transitional cell carcinoma of the bladder (December 2014 - June 2016) was done. We excluded cases with preoperative T4 staging, lymphadenopathy, prostatic specific antigen > 4 ng/dl, and cases with positive biopsies from the bladder neck, trigone, and/or prostatic urethra. Patients were divided into 2 groups, Group 1: standard radical cystectomy with orthotopic diversion (n = 51), Group 2: prostate capsule sparing cystectomy with orthotopic diversion (n = 45). Preoperative transrectal ultrasound and prostatic biopsies were done in Group 2 to exclude prostate cancer. We compared the urinary continence and erectile function in both groups after 6 months, 1, and 2 years. Results There was no significant difference between the groups regarding preoperative demographic data, tumor stage, grade, site by cystoscopy, and biopsy. Intraoperative monitoring showed no significant differences regarding blood loss, surgical complications, or operative time (2.5 ± 0.48 vs. 2.4 ± 0.45 h). There was a significantly higher percentage of continence and potency in Group 2 than in Group 1. Sixteen cases (35.6%) in Group 2 but only 4 cases (7.8%) in Group 1 developed large post-voiding residual urine and needed intermittent self-catheterization cleaning (p = 0.001). The tumor recurrence rate was not significantly different between the groups after 2 years (p = 0.3). Conclusion Prostate capsule sparing cystectomy is a good option in selected cases with better continence and potency and without compromising oncological outcomes after 2 years.

Abstract
PURPOSE We determined the likelihood that transurethral resection biopsy of the prostatic urethra adjacent to the verumontanum would detect prostatic involvement of urothelial carcinoma in patients with bladder carcinoma. MATERIALS AND METHODS We compared precystectomy transurethral resection biopsy specimens of the prostatic urethra with those of the matched radical cystoprostatectomy in 272 patients with urothelial carcinoma of the bladder. All prostates were evaluated by whole mount step sections. RESULTS Prostatic involvement by urothelial carcinoma was detected by transurethral resection biopsy or radical cystoprostatectomy in 101 patients (37.1%). Transurethral resection biopsy detected urothelial carcinoma in 72 cases with 71.3% sensitivity and 100% specificity. The overall accuracy of transurethral resection biopsy to detect urothelial carcinoma of the prostate was 89% (positive and negative predictive values 100% and 86%, respectively). Invasive prostatic urothelial carcinoma arising from the prostatic urethra was detected by transurethral resection biopsy in 21 of 26 patients (81%) while prostatic carcinoma in situ was detected in 39 of 52 (75%). Transurethral resection biopsy detected prostatic invasive urothelial carcinoma resulting from transmural invasion of a bladder tumor in 4 of 15 patients. CONCLUSIONS Prostatic involvement by urothelial carcinoma of the bladder was found in 37.1% of patients. Transurethral resection biopsy missed most tumors resulting from transmural invasion of the bladder primary lesion. Carcinoma in situ and invasive urothelial carcinoma arising from the prostatic urethra were detected in most cases. Transurethral resection biopsy of the prostatic urethra can complement staging and support clinical decision making with respect to neoadjuvant chemotherapy and planning for an orthotopic neobladder.

Abstract
En bloc removal of the prostate has traditionally been an integral component of radical cystectomy for men with bladder cancer owing to a high incidence of occult prostatic malignancy. However, the risk of functional morbidity following this procedure is considerable and can delay patient acceptance of cystectomy, which can adversely affect the long-term prognosis. Recently, some investigators have advocated prostate-sparing cystectomy (PSCx) to improve postoperative continence and potency rates, and this may also improve timely patient acceptance of cystectomy. Several of these PSCx series describe excellent functional results postoperatively and PSCx may also facilitate a laparoscopic approach, offering further dividends. However, valid concerns regarding the oncologic efficacy of this procedure still predominate and protocols for patient selection, technique and postoperative surveillance are not well defined. The concept of PSCx is arguably one of the most controversial topics in the field of bladder cancer today.

Abstract
OBJECTIVES Urothelial carcinoma (UC) is a multifocal disease that may develop in any location of the urinary tract, including the prostate. We analyze the types of prostate involvement due to UC, their diagnosis, risk factors and the clinical implications of this entity. MATERIAL AND METHODS Analysis of original, review articles and publications related to prostate involvement due to UC. The study included works published in the period of 1985-2011, most of which were obtained from the search in PubMed. RESULTS Prostate involvement due to UC has been observed frequently in both non-muscle invasive bladder cancer (NMIBC) series and prolonged follow-up (39%) as in radical cystectomy series (15-48%). Prostatic involvement may occur in the mucosa and ducts (superficial involvement) or prostate stroma (invasive involvement), a fact that has prognostic and therapeutic implications. Stromal involvement may have both a bladder and intraurethral origin. Carcinoma in situ, multifocality, bladder neck/trigone cancer, and previous history of tumor recurrence are the factors that have been m ore consistently associated to prostate involvement due to UC. The incidence of prostatic involvement by UC in patients with NMIBC increases over time when risk factors exist. In these cases, a prostatic urethral biopsy should be performed during the follow-up. Conservative treatment with transurethral resection and BCG is possible in case of superficial involvement of the prostatic urethra, assuming its risk of progression. Patients subjects to cystectomy and with prostate involvement due to UC have a greater risk of urethral recurrence. The elevated incidence of prostatic adenocarcinoma and prostatic involvement by UC in cystectomy specimens makes it necessary to be very selective when indicating prostate-sparing cystectomy. Chemotherapy may be an option in an attempt to improve survival of patients with prostatic stromal involvement. CONCLUSIONS Prostatic involvement by UC is not uncommon and it has important implications in the management of patients with NMIBC and in those who have an indication for or have undergone radical cystectomy.

Abstract
CONTEXT Decision making regarding the urethra before and after radical cystectomy due to urothelial carcinoma has always been controversial. OBJECTIVE To analyze the changes produced in the management of the urethra from the beginning of the cystectomy up to the present moment. EVIDENCE ACQUISITION Analysis of original articles and reviews obtained through a search in PubMed, related with the risk factors of urethral recurrence (UR) and with the management of the urethra in patients subjected to radical cystectomy. EVIDENCE SYNTHESIS At first, many authors recommended urethrectomy simultaneously with cystectomy. The identification of risk factors of the bladder tumor related with the appearance of UR limited the indication of prophylactic urethrectomy in patients with multifocal disease and with prostate tumor involvement. The development of orthotopic bladder substitutes (OBS) complicated the situation. The involvement the prostatic urethral tumor was maintained as the principal risk factor for UR, which then gave importance to its pre-cystectomy staging. Series of OBS observed a lower incidence of UR regarding patients with skin derivations, even in cases with prostatic urethral involvement. Prostatic urethral involvement stopped being a contraindication for OBS when the frozen section biopsy of the urethral margin was negative. CONCLUSIONS Currently, most authors agree that the intraoperative frozen section biopsy of the urethral margin will determine whether an OBS or urethrectomy should be performed. In spite of this, we have very few series in which this approach has been systematically used and with sufficient follow-up.

Abstract
OBJECTIVES To prospectively evaluate the incidence of transitional cell carcinoma (TCC) in the prostatic urethra and prostate in the cystoprostatectomy specimen, investigate characteristics of bladder tumours in relation to the risk of involvement of the prostatic urethra and prostate and examine the sensitivity of preoperative loop biopsies from the prostatic urethra. MATERIAL AND METHODS Preoperatively, patients were investigated with cold cup biopsies from the bladder and transurethral loop biopsies from the bladder neck to the verumontanum. The prostate and bladder neck were submitted to sagittal whole-mount pathological analysis. RESULTS The incidence of TCC in the prostatic urethra and prostate in the cystoprostatectomy specimen was 29% (50/175 patients). Age, previous bacillus Calmette-Guérin treatment, carcinoma in situ (Cis) in the cold cup mapping biopsies and tumour grade were not associated with the risk of TCC in the prostatic urethra/prostate. Cis, multifocal Cis (> or = 2 locations) and tumour location in the trigone were significantly more common in cystectomy specimens with TCC in the prostatic urethra and prostate: 21/50 (42%) vs 32/125 (26%), p=0.045; 20/50 (40%) vs 27/125 (22%), p=0.023; and 20/50 (40%) vs 26/125 (21%), p=0.01, respectively. Preoperative resectional biopsies from the prostatic urethra in the 154 patients analysed identified 31/47 (66%) of patients with TCC in the prostatic urethra/prostate, with a specificity of 89%. The detection of stromal-invasive and non-stromal involvement was similar: 66% and 65%, respectively. CONCLUSIONS The incidence of TCC in the prostatic urethra and prostate was 29% (50/175) in the cystoprostatectomy specimen. Preoperative biopsies from the prostatic urethra identified 66% of patients with such tumour growth. Our findings suggest that preoperative cold cup mapping biopsies of the bladder for detection of Cis add little extra information with regard to the risk of TCC in the prostatic urethra and prostate.

Abstract
OBJECTIVES The objective of this paper is to examine the contemporary incidence, diagnosis, and treatment of prostatic urothelial carcinoma and make recommendations on the current dilemmas of treating urothelial cancer of the prostate. METHODS A review of English-language literature from 1990 to the present was performed utilizing the U.S. National Library of Medicine's Pub Med database. Keywords used were urothelial cell carcinoma, prostatic urethral involvement, prostatic duct/acini involvement, carcinoma in situ. Bibliographies of reviewed articles were also searched. RESULTS Transitional cell carcinoma of the bladder with involvement of the prostate has been reported in multiple studies with an incidence between 12% and 48%. Stromal invasion of the prostate has a reported incidence between 7% and 17%. The incidence of primary transitional cell carcinoma of the prostate has been estimated at 1% to 4% of prostatic malignancies. Degree and depth of prostatic invasion has prognostic significance with 5-year survival rates being 100% for those with urethral mucosal involvement, 50% with ductal/acinar involvement, and 40% with prostatic stromal invasion. The actual anatomic path that urothelial carcinoma invasion occurs also has prognostic significance. Those with contiguous malignant involvement had a 7% 5-year survival rate compared with those with noncontiguous involvement and a 46% 5-year survival rate. CONCLUSIONS Prostatic urothelial carcinoma is often under appreciated and not well understood. Malignant involvement of different anatomic locations of the prostate (i.e., mucosa, ducts, acini, and stroma) influence not only diagnosis but treatment of disease. Although debate exists regarding optimal therapy for mucosal involvement, if the prostatic stroma is involved, radical cystoprostatectomy is the treatment of choice.

Abstract
Prostatic involvement by transitional cell carcinoma (pTCC) in patients with bladder cancer is a frequent finding, particularly in patients with high-grade invasive tumor and urothelial carcinoma in situ. Various patterns and levels of prostatic involvement have been described, and their impact in patients' management and their prognosis recognized. The role of prostatic urethral biopsy and intraoperative frozen section in the management of bladder cancer, tailoring to the bladder tumor stage is still not well defined and universally accepted. This review discusses the current understanding of the biology and histological patterns of pTCC and their clinical significance and management options. A rational approach for management of pTCC in patients with bladder cancer will be proposed on the basis of our experience and our review of literature.

Abstract
We reviewed the literature on urothelial carcinoma in the prostatic urethra and prostate. We concluded that the incidence of urothelial carcinoma in the prostatic urethra and prostate is probably underestimated. This fact warrants thorough follow-up of patients with high-risk bladder cancers and also whole-mount examination of the prostate after cystectomy to recognize the true incidence and extent of such tumor involvement. Resectoscope loop biopsy is the method of choice to detect urothelial carcinoma in the prostatic urethra/prostate and such biopsies should include the area around the verumontanum to ensure optimal sensitivity. Carcinoma in situ in the prostatic urethra should be treated with intravesical Bacillus Calmette-Guérin and a transurethral resection of the prostate prior to that treatment might increase the contact of Bacillus Calmette-Guérin with the prostatic urethra, improve staging and in itself treat the prostatic involvement. Conservative treatment of carcinoma in situ in the prostatic ducts is an option, although radical surgery is probably best for treating extensive intraductal involvement, since data on the former strategy are inconclusive. Patients with stromal invasion should undergo radical surgery. It is necessary to take the route of prostatic involvement into account when estimating prognosis in each individual patient, since contiguous growth into the prostate is associated with worse prognosis. Prospective studies using a whole-mount technique to investigate the prostate are needed to clarify both the role of different routes of prostate invasion and the prognostic significance of different degrees of prostate invasion. At cystectomy, when urothelial carcinoma is present in the prostatic urethra and/or prostate, it is necessary to balance the risk of urethral recurrence and decreased sexual function against opinion and expectations expressed by the patient during preoperative counseling regarding urinary diversion and primary urethrectomy.

Abstract
Transitional cell carcinoma of the prostate (TCCP) has become a well recognized entity, showing an increasing incidence due to the growing research awareness. TCCP is part of the well known pan-urothelial disease: the urologist, therefore, is strongly recommended to consider the prostate at any time in the management of superficial and invasive bladder cancer. Several cases are diagnosed in association with bladder cancer (secondary TCCP): primary prostatic transitional cell carcinoma arises ‘de novo’ as first tumour of the prostate urothelium and is rare. Prognosis depends on the prostate invasion degree. No reliable staging systems are presently available. Non-invasive TCCP can be successfully treated with conservative means (TUR +/- BCG), whereas stromal invasive TCCP must be aggressively treated with radical cystectomy. TCCP can interphere with surgeon's decisions about urinary diversion in patients undergoing radical cystectomy for urothelial cancer. (Urologia 2007; 74: 15–21)

Abstract
This study was conducted to explore the diagnosis and management of urothelial carcinoma of the prostate in superficial disease and carcinoma in situ, stromal invasion, primary urothelial carcinoma, and urethral recurrence after radical surgery. A consensus conference convened by the World Health Organization (WHO) and the Société Internationale d'Urologie (SIU) reviewed the diagnosis and management of urothelial carcinoma of the bladder. English-language literature about urothelial carcinoma of the prostate was identified and reviewed. Evidence-based recommendations for the diagnosis and management of urothelial carcinoma were made. Many recommendations were level 3 or 4 citations involving the diagnosis and management of superficial urothelial carcinoma; a few were level 2 citations. Level 1 citations related only to chemotherapy and radiotherapy in patients with stromal invasion, although these were not related specifically to invasive prostatic involvement. More than 130 reviewed citations are summarized in this review. Published reports on the diagnosis and treatment of superficial urothelial disease of the prostate primarily consist of short case series from individual centers. Prospective and multicenter trials are needed to identify the real incidence and the best management of these patients. In invasive disease of the prostate, the only large series were designed to investigate invasive bladder cancer.

Abstract
The indications for urethrectomy during cystectomy for bladder cancer have substantially changed during the last years. Many years ago, prophylactic urethrectomy was performed in most patients undergoing cutaneous diversion. Today, transitional cell carcinoma at the level of the prostatic urethra or at the bladder neck is recognized to be the most important risk factor of urethral recurrence. Since the development of bladder substitutions, the indications for prophylactic urethrectomy have been dramatically reduced. Pre - and intra operative evaluation of the prostatic urethra in men and that of the bladder neck in women is the major determinant in the appropriate treatment strategy for the urethra in patients with bladder cancer.

Intravesical Instillations with Bacillus Calmette-Guérin for the Treatment of Carcinoma In Situ Involving Prostatic Ducts. Eur Urol 2006; 49:834-8; discussion 838. [PMID: 16426729 DOI: 10.1016/j.eururo.2005.12.019] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2005] [Revised: 12/06/2005] [Accepted: 12/12/2005] [Indexed: 12/01/2022]
Abstract
OBJECTIVES Bacillus Calmette-Guérin (BCG) has proven its efficacy in the treatment of carcinoma in situ (CIS) of the prostatic urethra. We performed a retrospective study to evaluate the use of intravesical instillations of BCG in patients with carcinoma in situ involving prostatic ducts after complete transurethral resection (TUR). MATERIAL AND METHODS Eligibility for the study was CIS of the prostatic urethra involving prostatic ducts. Previous instillation with BCG was an exclusion criterion. Patients were treated with intravesical BCG Connaught (81 mg) administered once a week, over a 6-wk period. TUR loop biopsies of the prostate were performed only when a macroscopic tumor was present. RESULTS In this retrospective study of 11 patients, 8 (73%) presented with macroscopic tumor in the prostatic urethra. Ten patients (91%) had a simultaneous superficial bladder carcinoma. Eight patients (73%) had tumoral involvement of the bladder neck region. After a median follow-up of 27 mo (n=10 patients), the response in the prostatic urethra was 82%, and the response in the bladder due to superficial tumor recurrence was 64%. Two patients with residual ductal disease in the prostatic urethra were subsequently treated with cystoprostatectomy and are currently free of disease. In one of those patients, the cystoprostatectomy specimen did show prostatic stromal invasion. Another patient developed distant metastatic disease and died a few months after diagnosis. Thus, progression was encountered in two patients (18%). Currently, 90% of patients are alive without evidence of disease and 72.7% have benefitted from this bladder preservation strategy. CONCLUSION Intravesical BCG is a feasible treatment option for patients with CIS involving prostatic ducts. In this retrospective study, bladder preservation was successful in 8 of 11 patients (70%) and there was only one oncologic death. Obviously, these patients need a careful follow-up with cystoscopy and cytology to detect either recurrence or progression and in those with persistent disease after the initial BCG induction therapy, prompt cystectomy is indicated.

Abstract
PURPOSE To review understaging and outcome of patients who underwent radical cystectomy (RC) for high risk superficial bladder cancer after bacillus Calmette-Guérin (BCG) failure. PATIENTS AND METHODS We carried out a retrospective study of 62 cases in which RC was indicated for clinical stage Tis, Ta, T1 transitional cell bladder tumors that failed transurethral resection (TUR) and BCG treatment. We used BCG (81 mg/Connaught BCG) in patients with superficial grade 3 tumors and CIS. We considered BCG failure a high-grade recurrence at 3 months of the first BCG course or after 2 courses. RC indications, correlation between their clinical and pathological stage and the ensuing progress were analyzed. We assessed the existence of any pre-cystectomy clinical or pathological factor related to understaging and survival. RESULTS RC was performed in 22 patients with carcinoma in situ (CIS) (35%), 7 with Ta (11,2%), 31 with T1 (50%), and 2 with Tx tumors (3%). All 62 but one were high-grade tumors (grade 3 and/or CIS). Tumor was clinically understaged with stages pT2 or greater on the RC specimen in 17 patients (27%). The presence of tumor in the prostatic urethra at the moment of endoscopic staging before RC was the only factor associated with clinical understaging (p=0.003) and shorter survival (p<0.0002). Five-year disease-specific survival rate was significantly lower in understaged (38%) as compared with not-understaged patients (90%) after a median follow-up of 40-months (range 1-142) (p=0.006). Overall five-year disease-specific survival was 79%. CONCLUSIONS RC should be performed prior to progression in high risk superficial tumors that fail after TUR and BCG. In patients with clinical and pathological nonmuscle invasive disease, RC provides an excellent disease-free survival. One third of patients with HRSBT who underwent RC after BCG failure were understaged and had a shorter survival. Tumor in the prostatic urethra at endoscopic staging was the only factor associated to understaging and shorter survival.

Abstract
PURPOSE We describe the functional outcome on erectile function, continence and voiding, and local and distant cancer recurrence rates in 44 patients after sexuality preserving cystectomy and neobladder (prostate sparing cystectomy). MATERIALS AND METHODS A total of 44 males underwent cystectomy with preservation of the prostate, seminal vesicles and vasa deferentia, after which a Studer type neobladder was anastomosed to the prostate. Oncological outcome (disease specific survival, distant and local recurrence rates) and functional results (continence, voiding, erectile function) were determined. RESULTS At a median followup of 42 months, 13 (30%) patients died of cancer. All 13 experienced widespread disease, which was combined with a pelvic recurrence (pelvic recurrence rate 6.9%) in 3. The 3-year survival according to pathological stage was 86% for pT 2N0 or lower, 63% pT3N0 and 39% for node positive tumors (anyT Npos). Prostate cancer was diagnosed in 1 patient 5 years after treatment, and recurrent carcinoma in situ in the prostatic urethra in another patient. Complete daytime and nighttime continence was achieved in 95.3% and 74.4%, respectively. Incontinence during day and night could be managed by 1 pad per day/night in 4.7% and 20.9%, respectively, while 4.7% needed more than 1 pad per night. Erectile function could be determined in 40 patients, and potency was maintained in 77.5%, impaired in 12.5% and absent in 10%. CONCLUSIONS Functional results with regard to erectile function and urinary continence after prostate sparing cystectomy are good. Oncological results have been promising, but need to be confirmed after longer followup and in larger trials.

Abstract
OBJECTIVE To evaluate the oncological outcome and functional results of prostate-sparing cystectomy (PSC), proposed for treating bladder cancer, used since 1999 in our institution in an attempt to preserve male sexuality and to increase continence after cystectomy. PATIENTS AND METHODS Between January 1999 and December 2001, 111 men were candidates for cystectomy; 42 were selected for a prostatic capsule- and seminal-sparing cystectomy with orthotopic urinary diversion. All patients had clinically organ-confined tumours (clinical stage </= T2, N0M0). The first stage of the procedure was a transurethral resection of the prostate to exclude the involvement of transitional cell carcinoma (TCC) in the prostate. RESULTS Eight patients were excluded from PSC because they had TCC (seven) or prostate adenocarcinoma (one). The mean age of the remaining 34 patients was 61 years and all underwent PSC. After a mean follow-up of 26 months, seven patients (21%) had a recurrence; one developed a local recurrence, there were widespread metastases in six (18%), and five had histologically confirmed organ-confined tumour (T1-2N0M0). Rates for daytime and night-time continence were 90% and 85%, and in 29 patients potency was unchanged. CONCLUSION These early results suggest that PSC is not equivalent to radical cystoprostatectomy for bladder cancer control, despite marked improvements in the functional results. Moreover, in carefully selected patients this approach appears to dramatically increase an unusually high metastasis rate. Therefore, the indications for PSC should be either clearly well defined or abandoned in these patients.

Abstract
Bacillus Calmette-Guerin (BCG) instillation therapy is now a standard therapy for high-risk superficial bladder cancer patients. Although the complete response rate is approximately 70%, extra-vesical progression is sometimes observed. In particular, those patients who present a positive urinary cytology even after complete response from bladder lesion should be thoroughly examined. We present two cases of stromal invasion of the prostate after complete remission by BCG therapy of carcinoma in situ of the ureter and bladder found by transrectal prostate biopsy.

Abstract
Superficial bladder cancer comprises the majority of bladder tumors presenting today. Although the word "superficial" connotes a benign behaving curable disease, it is clear from long-term observations of the natural history of the disease that there are two discrete entities of superficial bladder cancer, one a low-grade innocuous tumor and the other a high-grade potentially lethal tumor. These two entities vary in their histologic appearance, risk of tumor recurrence, pattern of recurrence, and risk of tumor progression. Although work on prognostic markers is promising, currently none are sufficiently reliable; therefore, clinical factors are used to identify patients with a higher risk of tumor recurrence or progression. These include the tumor stage, tumor grade, number of tumors (multifocality), presence of associated carcinoma in situ, and initial response to therapy. Surveillance schedules are individualized based on the risks for recurrence and progression. High-risk patients who undergo successful treatment of their bladder tumor initially recur more commonly in the bladder, but have a progressive risk over time of extravesical recurrences necessitating lifelong surveillance of the bladder, urethra, prostate, and upper tracts. Patients who are refractory to conservative management with intravesical therapy and TUR should be apprised of the risks for further conservative treatment and consider early radical cystectomy in an attempt to improve long-term survival. The advent and long-term success of orthotopic continent diversions has made the decision for early radical cystectomy more palatable to both the patient and physician.

Abstract
After the introduction of bladder replacement procedures, the indications for prophylactic urethrectomy have become more and more restricted. While years ago, a prophylactic urethrectomy was performed in many patients with cutaneous diversions, it has become clear that only patients with invasion by transitional cell carcinoma at the level of the prostatic urethra or bladder neck have a substantial risk of developing subsequent urethral recurrence. The pre- or intra-operative assessment of the prostatic urethra in males and of the bladder neck in females is the key to appropriate management of the urethra in patients with bladder cancer.

Abstract
BACKGROUND Transitional cell carcinoma of the prostate in patients with bladder cancer appears to influence the prognosis and affects the decision about therapeutic modality. Therefore, it is important to characterize transitional cell carcinoma associated with bladder cancer. METHODS From April 1980 to December 1998, 81 male patients underwent total cystoprostatectomies for transitional cell carcinoma of the bladder. The 81 cystoprostatectomy specimens were examined to clarify the characteristics of prostatic involvement by transitional cell carcinoma. The extent, origin, mode of spread and risk factor of prostatic involvement as well as the prognosis were investigated. In 13 of 15 patients with prostatic involvement the prostate was examined by sequential step sections. RESULTS Prostatic involvement was observed in 15 of 81 patients (18.5%). Prostatic urethral involvement, invasion to prostatic duct/acinus, prostatic stromal invasion and extraprostatic extension and/or seminal vesicle involvement were recognized in 12 (80%), 14 (93.3%), six (40%), and five (33.3%) of the 15 patients, respectively. Twelve of the 15 patients (80%) with prostatic involvement had papillary or non-papillary tumors (i.e. carcinoma in situ) both in the prostatic urethra and prostatic duct. In 10 of these 12 patients (88.3%), there was contiguity between prostatic urethral and ductal tumors. Seven of the 23 patients (30.4%) with carcinoma in situ of the bladder showed prostatic involvement, which increased to 50% in the presence of carcinoma in situ of the trigone or bladder neck. CONCLUSIONS Eighty per cent of the patients with prostatic involvement showed papillary or non-papillary tumors both in the prostatic urethra and prostatic duct. There was a high level of contiguity between both tumors. Patients with carcinoma in situ of the trigone or bladder neck revealed significantly higher incidence of prostatic involvement.

Abstract
Orthotopic bladder replacement after total cystoprostatectomy for bladder cancer has gained broader use. Continent diversion has historically increased the complexity of the surgical procedure, often discouraging its adoption by many urologists. Absorbable staples on a GIA* instrument became available in 1992 and have been incorporated into reservoir formation in this preliminary study. A novel W-shaped ileal reservoir entirely fashioned from absorbable staples using the GIA and TA instruments has been developed and used in 15 patients undergoing cystoprostatectomy. The advantages of this technique are its simplicity and the speed with which the reservoir can be fashioned. In the first 15 patients operative time to construct the reservoir ranged from 12 to 21 minutes. Functional aspects of urodynamic studies and continence appear comparable to those of other ileal reservoirs. These preliminary data justify comparative trials on an expanded scale.

Abstract
An aggressive evaluation of extravesical sites of disease in patients with clinically unconfirmed positive urinary cytology findings is indicated only in previously untreated asymptomatic or symptomatic patients (group 1) and in those with a complete response to intravesical therapy who are without evidence of disease for 1 year (group 4). Patients who have positive urinary cytology findings immediately after complete transurethral resection of bladder tumors or intravesical therapy will almost always have recurrent bladder transitional cell carcinoma and do not require aggressive extravesical evaluation initially. Transurethral resection prostate biopsy between the 5 and 7 o'clock positions along the entire length of the prostatic urethra is the technique of choice for detecting transitional cell carcinoma of the prostate, since other less invasive techniques frequently underestimate the extent of disease. In the absence of radiographic disease, bilateral ureteral lavage cytology is the technique of choice to identify the upper tract as the source of a positive urinary cytology result. Rigid and flexible ureteropyeloscopy should be performed only in the presence of radiographic or cytological evidence of upper tract transitional cell carcinoma, or in patients with a history of upper tract disease who have suspected relapse on the basis of a positive urinary cytology result.

Abstract
The distribution of any involved prostatic urethra, ducts and acini by urothelial carcinoma was studied to determine an adequate sampling method for detecting prostatic involvement using the maps of 38 cystoprostatectomy specimens. A total of 31 patients had prostatic duct and acini involvement, while 7 had prostatic urethral involvement alone. However, the distribution of the involved prostatic urethra, ducts and acini varied. In 29 of the 31 patients (93.5%) with prostatic duct and acini involvement, urethral carcinoma in situ and/or superficial gland involvement (an involvement of the afferent ducts within a few millimeters of the urethral mucosa) at the 5 and/or 7 o'clock position of the verumontanum portion was identified. In 7 patients with prostatic urethral involvement alone 2 had carcinoma foci at the 5 and/or 7 o'clock position of the verumontanum portion. Furthermore, the frequency of deeper gland involvement (an involvement of true prostatic acini except for superficial glands) was higher in patients with superficial gland involvement at the 5 and/or 7 o'clock position of the verumontanum portion (57.7%) than in patients without such involvement (20.0%). Therefore, this study emphasizes that a transurethral resection biopsy containing prostatic tissue at the 5 and/or 7 o'clock position of the verumontanum portion substantially improves the detection of prostatic duct and acini involvement in bladder cancer patients. Moreover, if the prostatic superficial glands are involved at the 5 and/or 7 o'clock position of the verumontanum portion, the potential involvement of the deeper glands should also be suspected.

Abstract
We reviewed the clinical courses of 86 men after radical cystoprostatectomy for transitional cell carcinoma of the bladder to determine who were at highest risk for urethral recurrence. We assessed patients for prostatic involvement as well as tumor extent in the bladder and distal ureters. Of the 30 patients with tumor in the prostate 11 (37%) suffered urethral recurrences. Of the 56 patients with all other types of tumor involvement patterns exclusive of disease in the prostate only 2 (4%) had recurrence. We recommend rigorous screening for transitional cell carcinoma of the prostate before cystectomy. Prophylactic urethrectomy is indicated for patients with prostatic involvement, while those without such involvement may be considered at low risk for urethral recurrence.
