Pelvic exenteration as treatment of recurrent or advanced gynecologic and urologic cancer.

Pelvic exenteration is used as therapeutic option for advanced or recurrent cancer in the pelvis. We determined the complications of and the survival after pelvic exenteration. The study was performed as a retrospective cohort (n = 62) study from January 1, 1989, until January 1, 2000. Descriptive statistics were used. Survival was estimated according to the Kaplan-Meier life table. The operative mortality was 1.6%. Seventy-five percent of the patients had postoperative complications of which ileus and urinary tract infection were the most common. Late complications occurred in 83% of the patients. Recurrent disease was observed in 38% of the women, whereas 50% had died on January 1, 2000. Five-years disease-free and overall survival were 42% (confidence interval [CI] +/- 14%) and 46% (CI +/- 14%), respectively. Elderly patients (> 70 years old) do not experience more complications. Despite considerable morbidity, pelvic exenteration is a therapeutic option for survival, even for patients of 70 years and older.

Quality of life after pelvic exenteration.

OBJECTIVES: Pelvic exenteration, for gynecological and urological cancer, is an extensive and mutilating procedure. The 5-year survival rate is fairly good (40-60%), but little is known about the long-term quality of life. METHODS: In this retrospective cohort study, the quality of life was assessed using the EORTC QLQ-C30 (version 3.0) and the EORTC QLQ-OV28 questionnaires. RESULTS: Healthy females and those who underwent pelvic exenteration for a gynecological or urological malignancy reported comparable levels of emotional functioning and general quality of life. More physical, sexual, and social problems were, however, noted after exenteration. Younger patients and patients who underwent total pelvic exenteration had the most difficulty in adapting to daily life, disease, and treatment. They also had a worse body image, and the influence of the operation on their sex life was greater compared to other patient groups of this study. CONCLUSION: Despite the immense effect of pelvic exenteration on physical, sexual, and social functioning, women who underwent this procedure reported similar levels of emotional functioning and general quality of life compared to healthy women. Adaptation and the mechanism of response shift presumably play an important role.

Nocturia: impact on quality of life in a Dutch adult population.

OBJECTIVE: To estimate the effect of nocturia on quality of life (QoL) and to assess the associated effects of sleep problems. SUBJECTS AND METHODS: From a random sample of Dutch adults (>/= 18 years old) 1000 were selected after stratification to complete a written questionnaire. Respondents (819) were distributed over three groups: a target group (189, who felt bothered by >/= one void/night); a reference group 1 (120 reporting >/= two voids/night but with no bother); and reference group 2 (510, with 0-1 voids/night). Nocturia, other lower urinary tract symptoms and perceived impact on life were measured using the Bristol Lower Urinary Tract Symptoms Questionnaire (B-LUTS). Sleep problems were measured using the Sleep Wake Experience List (SWEL) and QoL using two subscales from the RAND-36, i.e. 'physical functioning' and 'mental health'. RESULTS: The perceived impact on life was highest in the target group (P < 0.05), which also had more sleep problems and scored lower on the QoL scores than both reference groups (P < 0.05). Statistically significant differences in mental health and physical functioning between the target and reference groups became insignificant after correcting for sleep problems, indicating that the effect of nocturia (with bother) is mediated by sleep problems. CONCLUSIONS: Nocturia may lead to sleep insufficiency and consequently to a decrease in mental and physical health. Patients who consult a doctor for nocturia should thus be treated adequately. In addition, it is worthwhile for doctors to routinely check if patients who contact them for sleep problems also have nocturia.

Comparison of intra-luminal versus intra-tumoural temperature measurements in patients with locally advanced prostate cancer treated with the coaxial TEM system: report of a feasibility study.

A study was performed on regional hyperthermia for patients with locally advanced prostate carcinoma. The primary objective was to analyse the thermometry data with an emphasis on the possibility of replacing invasive thermometry by tumour-related intra-luminal thermometry. Fourteen patients were treated with a combination of conformal external beam radiotherapy (70 Gy) and hyperthermia. Hyperthermia was delivered using the Coaxial TEM system, one treatment per week, to a total of five treatments. Thermometry was performed in bladder, urethra, rectum and esophagus. Invasive thermometry in the prostate was carried out during one or two treatments for each patient by placing transperineally a central and a peripheral catheter. Heterogeneous temperature distributions were measured in the prostate. The mean average invasive temperature range was 1.1 degrees C. Due to the temperature heterogeneity and a limited number of thermometry sensors (mean 7, range 2-13), large variability between treatments and patients existed regarding achieved temperatures and dose. The mean invasive T90 was 40.2 +/- 0.6 degrees C and T50 was 40.8 +/- 0.6 degrees C. The mean Cum min T90>40.5 degrees C per treatment was 22 (range 0-50). Importantly, intra-luminal temperatures did not reliably predict invasively measured temperatures. Invasive thermometry, therefore, remains compulsory to calculate a thermal dose for an individual patient. Changes in temperature during treatment, measured by the urethral sensors, corresponded well with changes in temperature measured by the individual invasive sensors. Similar comparison of rectal temperature changes with intra-prostatic temperature changes was not as predictive. The similarity in temperature changes between the urethral and interstial sites, suggests that urethral temperatures are sufficient for treatment optimization. The SAR profile did not correspond with the temperature profile indicating heterogeneous perfusion. Although regional hyperthermia in combination with external beam radiotherapy for locally advanced prostate carcinoma is clinically feasible, the question on the importance of invasive thermometry remains.

Pharmacological modulation of ureteral peristalsis in a chronically instrumented conscious pig model. I: Effect of cholinergic stimulation and inhibition.

PURPOSE: We evaluated in vivo the role of muscarinic receptors on ureteral peristaltic frequency and contraction force in a large animal model using pharmacological manipulation. MATERIALS AND METHODS: A total of 12 female pigs weighing a mean +/- SEM of 72 +/- 4 kg were chronically instrumented using an electronic pressure monitoring catheter in the right ureter. Furthermore, nephrostomy, arterial, venous and cystostomy catheters were placed. Ureteral peristalsis was repeatedly recorded before and after the administration of atropine and carbachol. RESULTS: Systemic and local effects of the 2 agents were observed. Compared with controls we recorded an increase in mean ureteral peristaltic frequency (2.0 +/- 0.3 versus 1.6 +/- 0.6 minutes-1, p <0.05) and mean contraction force (50.1 +/- 1.4 versus 45.3 +/- 1.7 cm H(2)O, p <0.05) during renal pelvis perfusion with 0.25 ml per minute saline. Administration of atropine or carbachol modulated neither the force of contraction nor the frequency of ureteral peristalsis in vivo (p >0.05). CONCLUSIONS: Smooth muscle motor activity at the mid and distal ureter is not modulated by muscarinic receptors. Peristaltic frequency is directly related to the pyelocaliceal load during a rate of diuresis not exceeding animal normal diuresis plus 0.25 ml per minute. Ureteral contraction force increases only in the mid ureter with increased diuresis.

Reduced specificity of 5-ALA induced fluorescence in photodynamic diagnosis of transitional cell carcinoma after previous intravesical therapy.

OBJECTIVE: Photodynamic diagnosis (PDD) for the detection of bladder cancer has become a diagnostic tool in several hospitals. Several studies have reported different rates of false positive biopsies using 5-aminolevulinic acid induced fluorescence. In this study we evaluated the effect of previous intravesical therapy on the false positive biopsy rate. METHODS: Two hours prior to endoscopy 1.5g ALA dissolved in 50ml 1.4% NaHCO(3) solution was instilled intravesically. For fluorescence excitation a blue light source (D-light, Karl Storz) was used. Under white and fluorescence light guidance, tumor locations were recorded, cold cup biopsies were taken and tumors were resected. Patients were divided into 3 groups, last intravesical therapy (IVT) less than 6 months prior to PDD, last IVT longer than 6 months before PDD and no previous IVT. RESULTS: In total 917 biopsies were taken in 249 procedures of fluorescent and non-fluorescent areas. White light endoscopy revealed 270 and PDD 378 of in total 390 tumors, resulting in a sensitivity of 97% and specificity of 49% for PDD. Pathologic evaluation considered 270 fluorescent biopsies as false positive. The rate of false positive biopsies was 25.7% in the group No IVT, 30.6% in the group PDD-IVT >6 months, whereas in the group "within 6 months after intravesical therapy" the rate was 39.6% (p<0.025). When premalignant lesions such as dysplasia II are considered tumor the difference between the groups is even more significant (p<0.001). CONCLUSIONS: The procedure has a high sensitivity for superficial bladder cancer and decreases the number of overlooked lesions. Recent intravesical therapy results in significantly more false positive fluorescent biopsies. Since patient outcome might predominantly be determined by the early detection and subsequent treatment of (pre)malignant tissue we suggest that PDD is justified even shortly after intravesical therapy.

Self-expanding stent insertion for urethral strictures: a 10-year follow-up.

OBJECTIVE: To evaluate the safety and efficacy of the Urolume endourethral self-expandable metallic stent (American Medical Systems, MI, USA) in treating urethral strictures, based on a follow-up of> 10 years. PATIENTS AND METHODS: Between November 1989 and June 1990, the Urolume stent was inserted into 15 patients (aged 25-77 years) who had recurrent urethral strictures. The mean duration of stricture before stent insertion was 10.9 years. The patients (all men) were followed using a questionnaire and uroflowmetry, and if necessary, retrograde cysto-urethrography and/or urethroscopy and/or X-ray urodynamics. RESULTS: Two failures were caused by excessive tissue proliferation in the stent, which ended in stent removal or a suprapubic catheter. Another two stents were removed because of discomfort or pain. Two patients developed stenosis in the stent after 7 and 9 years. In the final evaluation only two of the 15 patients were satisfied with their stent. The mean maximum urinary flow rate at the last follow-up was 15 mL/s, and half the patients noted 'stent' incontinence. Lower urinary tract infections, urge and stress incontinence, and discomfort with ejaculation, were all symptoms perceived at the last follow-up. CONCLUSION: The long-term results of the Urolume stent in this study weaken the optimistic early results. Only two of the 15 patients were satisfied with their stent.

Prognostic factors in localised prostate cancer with emphasis on the application of molecular techniques.

Prostate cancer is the most prevalent malignancy in males in the Western world and the second leading cause of male cancer death. Prostate specific antigen (PSA) based screening and case finding leads to identification of early stage prostate cancer. It is often difficult to discriminate between patients that need curative treatment and those that can be managed conservatively. Prognostic factors are used to make this clinical decision. Based on the classification proposed by the American College of Pathologists and the World Health Organisation, selected prognostic factors in prostate cancer are described. Clinical applicable factors are stage, grade and serum PSA. Prognostic factors that are not routinely used (for various reasons) are ploidy, histological type and cancer volume in needle biopsies. All other factors (including circulating tumour cells, angiogenesis, growth factors, proliferation rate, apoptosis, nuclear morphometry, neuroendocrine differentiation, loss of chromosomal regions, tumour suppresser genes and adhesion molecules) are promising as prognostic factor although currently their use in clinical decisions is not recommended. The role of these factors in prostate cancer growth and their predictive value are discussed. The rapid developments in molecular techniques allow assessment of structure or function of thousands of genes in a prostate biopsy sample. We expect that molecular characterisation of tumour material will become a clinically important tool to predict prognosis in patients with localised prostate cancer.

Symptoms, prostate volume, and urodynamic findings in elderly male volunteers without and with LUTS and in patients with LUTS suggestive of benign prostatic hyperplasia.

OBJECTIVES: To estimate the differences in symptoms, prostate volume, and urodynamic variables of symptom-free elderly volunteers, volunteers with lower urinary tract symptoms (LUTS), and urologic patients with LUTS suggestive of benign prostatic hyperplasia. METHODS: The study included 14 male volunteers without LUTS, 17 male volunteers with LUTS, and 565 urologic patients with LUTS who met the criteria of the International Consensus Committee on Benign Prostatic Hyperplasia. They were older than 50 years, they voided more than 150 mL during free uroflowmetry, their residual volume and prostate volume were estimated, and their American Urological Association symptom scores were collected. All men were also evaluated by urodynamic studies. RESULTS: The prostate volume, residual volume, urethral resistance factor, and symptom scores were significantly lower and the maximal free flow rate and effective capacity significantly higher in the symptom-free volunteers than in the volunteers and patients with LUTS. Except for prostate volume, the variables in volunteers with LUTS closely approximated those of the patients with LUTS. The volunteers with LUTS had a smaller prostate volume than did the patients with LUTS. Nevertheless, the maximal free flow rate, symptoms, degree of obstruction, and prevalence of residual volume did not differ between the two groups. Men with an unstable bladder were present in all groups. CONCLUSIONS: Symptom-free volunteers had smaller prostate volumes, less residual volume, lower symptom scores, a lower urethral resistance factor, a higher maximal free flow rate, and a higher effective capacity than those with LUTS. Except for a smaller prostate volume, the findings in the volunteers with LUTS closely approximated those of the urologic patients with LUTS.

Interactions between prostate volume, filling cystometric estimated parameters, and data from pressure-flow studies in 565 men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia.

The aim of this study was to establish the characteristics and to investigate the interactions between prostate volume, degree of obstruction, bladder contractility, the prevalence of residual volume, bladder compliance, bladder capacities, and the prevalence of instability in a large, well-defined group of men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). The 565 consecutive men included in this study met the criteria of the International Consensus Committee on BPH and voided more than 150 mL during uroflowmetry. Their residual urine volume and prostate size were estimated, and filling cystometry and pressure-flow studies were performed. Fifty-three percent of the men appeared to have obstruction. We found a positive correlation between prostate volume and Schäfer's obstruction grade, except that mean prostate volume decreased at Schäfer's grades 5 and 6. Significant negative correlations existed between Schäfer's grade and cystometric bladder capacity and effective capacity. Bladder outlet obstruction results in incomplete emptying. Of all men, 26% had a significant residual volume ( > 20% of cystometric capacity). Thirty-nine percent did not have residual volume. Of the 565 men, 46% had an unstable bladder. In particular, patients with an unstable bladder in the sitting and lying positions have a significantly higher Schäfer's grade and contractility grade and a significantly lower cystometric and effective bladder capacity compared with patients without instability. Patients with a residual volume or instability were significantly older. We conclude that in men with LUTS suggestive of BPH, abnormalities of bladder and bladder outlet function vary greatly and have complex mutual interactions.

One 24-hour frequency-volume chart in a woman with objective urinary motor urge incontinence is sufficient.

OBJECTIVES: To determine whether one 24-hour frequency-volume (FV) chart in a woman with objective urinary motor urge incontinence is sufficient to gain insight into her voiding habits. METHODS: Retrospectively, women 18 years old and older with urodynamically confirmed urinary motor urge incontinence without neurologic disease or other urologic pathologic findings, who correctly completed two or three 24-hour FV charts during normal daily life, were studied. For each patient, we compared the voiding parameters (mean voided volume, diuria, nocturia, minimum and maximum voided volumes, and total voided volume) and fluid intake calculated from the first FV chart with the same data calculated from all the FV charts. RESULTS: Ninety-eight adult women were recruited. A marked dropout occurred, and 60 patients remained to be evaluated (mean age 54.5 +/- 15.5 years). The calculated voiding parameters agreed with those in published reports. Strong associations existed between all voiding parameters and fluid intake calculated from the first FV chart and those calculated from all FV charts (P <0.001 for all parameters). Compared with the well-known variability, the differences between the voiding parameters calculated from the first FV chart and those from all charts were small. These results agreed with studies in other patient groups (benign prostatic hyperplasia and interstitial cystitis) that analyzed the use of only one 24-hour FV chart. CONCLUSIONS: The use of only one 24-hour FV chart completed during normal daily life by a woman with objective urinary motor urge incontinence is sufficient to gain insight into her voiding habits.

Prevalence and bothersomeness of lower urinary tract symptoms in benign prostatic hyperplasia and their impact on well-being.

PURPOSE: We established the prevalence and bothersomeness of symptoms and their impact on well-being in a large group of strictly selected men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Included in our study were 475 consecutive men who met the criteria of the International Consensus Committee on BPH and voided more than 150 ml. during uroflowmetry. International Prostate Symptom Scores and quality of life score were determined. We included the 7 bothersomeness questions of the Symptom Problem Index and the 4 of the BPH Impact Index of the American Urological Association Measurement Committee. These questions refer to the degree of bothersomeness caused by urinary problems and how they affect various health domains. RESULTS: The symptoms with the highest prevalence based on mean scores were weak urinary stream, frequency and urgency. Urgency, nocturia and hesitancy were the most bothersome symptoms. Patients were only discouraged from performing normal daily activity when the symptom index exceeded 20. Incomplete emptying and frequency bothersomeness correlated strongly, and weak urinary stream and hesitancy bothersomeness correlated weakly with all health and quality of life domains. CONCLUSIONS: Weak urinary stream, frequency and urgency were the most prevalent symptoms, while urgency, nocturia and hesitancy were the most bothersome symptoms. In contrast to weak urinary stream and hesitancy, the bothersomeness of incomplete emptying and frequency was strongly associated with well-being.

Testicular microlithiasis, a premalignant condition: prevalence, histopathologic findings, and relation to testicular tumor.

OBJECTIVES: To perform a retrospective analysis concerning the prevalence of testicular microlithiasis (TM). In patients with TM, the association of TM with testicular tumor, histopathologic findings, and follow-up were studied. METHODS: During a 6-year period at the Central Military Hospital or the University Medical Center in Utrecht, The Netherlands, ultrasonography of the testis was performed in 1535 patients. Patient records, ultrasound images, and histopathologic specimens were reviewed. Follow-up was performed in patients with TM. RESULTS: In 63 patients (4.1%), with a mean age of 35.4 years (range 19 to 74), TM was diagnosed at ultrasonography. In 29 of these patients (46%), a concomitant testicular tumor was diagnosed. A statistically significant correlation was found between TM and the presence of a testicular tumor (P <0.001; chi-square test). No significant correlation was found concerning the respective positions of the TM and the tumor in the testis, type of calcification, and histologic type of the tumor. In 34 patients, TM was found without a malignancy at diagnosis (mean age 39.2 years; range 19 to 69). Follow-up was possible in 31 patients. During the follow-up period (median 61.8 months), 1 patient developed a testicular tumor. CONCLUSIONS: A correlation was found between TM and testicular tumor. Because an increasing number of studies have reported patients with TM who developed a testicular tumor, TM should be regarded as a premalignant condition, which necessitates follow-up. Urologists should consider testis biopsy in patients with TM.

Symptoms and quality of life versus age, prostate volume, and urodynamic parameters in 565 strictly selected men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia.

OBJECTIVES: To investigate the associations of symptoms and quality of life with age, prostate volume, and urodynamic parameters in a large group of strictly selected men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. METHODS: The 565 consecutive men met all the criteria of the International Consensus Committee on benign prostatic hyperplasia and voided more than 150 mL during uroflowmetry. The residual volumes and prostate sizes were estimated. The International Prostate Symptom Score (IPSS) and quality-of-life score were collected and urodynamic evaluations performed. RESULTS: The prostate volume and obstruction grade were not, but low detrusor contractility and low bladder capacity were, significantly associated with symptoms. Except for nocturia, older men presented with lower voiding scores on the IPSS. The presence of a residual urine volume hardly influenced patients' symptoms and quality of life. Men with an unstable bladder scored higher on frequency, urgency, and nocturia on the IPSS, but the symptom index and quality-of-life score were not affected by the presence of an unstable bladder. Because of the high variability and subjective interpretation of symptoms and because urodynamic parameters may have opposite implications than symptoms and vice versa, associations were still weak. CONCLUSIONS: Except for nocturia, older men had lower voiding scores on the IPSS. Prostate volume and obstruction grade were not, but low detrusor contractility and low capacities were, associated with the symptom index. The presence of an unstable bladder and/or residual volume was hardly associated with the symptom index or quality-of-life score. Although we used a large group of strictly selected men, the associations were still weak.

Data from frequency-volume charts versus symptom scores and quality of life score in men with lower urinary tract symptoms due to benign prostatic hyperplasia.

OBJECTIVE: The aim is to study the relations between reported data on frequency-volume charts and the American Urological Association (AUA) symptom scores and quality of life score. METHODS: Males with lower urinary tract symptoms due to benign prostatic hyperplasia (BPH), were consecutively included in the study if they met the criteria of the International Consensus Committee on BPH, they voided >150 ml during uroflowmetry, residual volume and prostate size were estimated and frequency-volume charts were completed correctly. From the frequency-volume charts, voiding habits and fluid intake in the daytime and at night were evaluated. RESULTS: In the included 160 men no correlation was found between total urine production at night or in the daytime and symptom index or quality of life score. Nycturia was correlated with symptom index, but surprisingly not with quality of life score. Small voided volumes at night and in daytime are attended by high symptom index and high quality of life score (= low quality of life). Diuria has a high impact on symptom index and quality of life score. Men who completed frequency-volume charts during 3 or more daytime periods (68%) had a significantly higher symptom index than those who completed only 1 or 2 daytime periods (32%). CONCLUSIONS: High diuria, and small voided volumes at night and in daytime contribute significantly to high symptoms and low quality of life. Nycturia correlated with AUA symptom index but surprisingly not with quality of life score.

Urethral resistance factor (URA) versus Schäfer's obstruction grade and Abrams-Griffiths (AG) number in the diagnosis of obstructive benign prostatic hyperplasia.

Different methods of analyzing pressure/flow plots to quantify bladder outlet resistance in men with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) were developed in the past. The aims of this study were to quantify the degree of agreement between the diagnosis of obstruction by the different methods, and to compare the applicability of the different methods in the evaluation of bladder outflow conditions, in a large group of these men. In consecutive men with LUTS basic initial evaluations, recommended diagnostic tests, and urodynamic investigations were performed. From pressure/flow studies, the group-specific resistance factor (URA), Schäfer's obstruction grade, and Abrams-Griffiths (AG) number were estimated. Men with 21 cm H(2)O < or = URA < or = 29 cm H(2)O and men with Schäfer's grade equal 2 were classified as equivocal. In conformity with the provisional ICS definition, men with 20 < or = AG number < or = 40 were classified as equivocal. In 78% of the 565 included men Schäfer's classification agreed with URA classification. In 82% ICS classification agreed with URA classification. Most agreement (94%) existed between Schäfer's classification and ICS classification. All differences were near the points of intersection of the different boundaries, and a decision whether to perform surgery on a patient is not likely to be influenced by this disagreement. Males with relatively low detrusor pressure at maximum flow and relatively low maximum flow had a high prevalence among those in whom URA and Schäfer's classifications and among those in whom URA and ICS classifications differed.

Effect of diabetes mellitus on lower urinary tract symptoms and dysfunction in patients with benign prostatic hyperplasia.

This article reviews the recent literature on men with diabetes mellitus (DM) and concomitant lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Diabetes is reported to be associated with greater BPH symptom severity. Men with non-insulin-dependent diabetes had the highest median annual prostate growth rate compared with those who had other metabolic disease. Urodynamic evaluations in the reviewed studies were absent. Extensive diagnostic evaluations with urodynamics in our outpatient department revealed that patients with LUTS suggestive of BPH and with concomitant DM hardly differed from those without DM.

Analysis and reliability of data from 24-hour frequency-volume charts in men with lower urinary tract symptoms due to benign prostatic hyperplasia.

OBJECTIVES: The aims of this study were to analyse the data from frequency-volume charts and to study the reliability of these charts in men with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). METHODS: Males with LUTS due to BPH were consecutively included in the study if they met the criteria of the International Consensus Committee on BPH, voided more than 150 ml during uroflowmetry, residual volume and prostate size were estimated and frequency-volume charts were completed correctly. From the frequency-volume charts, voiding habits and fluid intake were evaluated. RESULTS: 160 patients could be included. Another 28 patients who met all other criteria did not complete the frequency-volume charts correctly. Agreement exists between reported voided volumes in the literature and those found by us. We found a significant correlation (p<0.001) between nycturia and score on symptom question 7, and between diuria and score on symptom question 2 of the AUA symptom index. The difference between results obtained from frequency-volume charts completed during 24 h and those obtained from charts completed during three or more 24-hour periods was negligible with respect to the variation of data at an individual level. CONCLUSION: Frequency-volume charts are reliable in the investigation of patients with LUTS due to BPH. Reporting on frequency-volume charts during just 24 h is sufficient to gain insight into their voiding habits during normal daily life.

Cowper's syringocele: symptoms, classification and treatment of an unappreciated problem.

PURPOSE: Cowper's syringocele is a rare deformity in the male urethra that is a distention of the duct of the bulbourethral (Cowper's) gland. We report on 7 cases, review the symptoms and pathophysiology, and propose a simplified classification of this uncommon lesion. MATERIALS AND METHODS: We reviewed 7 cases of Cowper's syringocele diagnosed from 1997 to 1998 at our hospital. RESULTS: Cowper's syringocele was diagnosed in 7 patients 25 to 51 years old with persistent post-void dribbling, frequency, urethral pain, hematuria or sudden urethral discharge. Diagnosis was made with urethrocystoscopy or retrograde urethrogram. Cowper's syringocele may be closed (a distended cyst-like swelling in the wall of the urethra) or open (an opening enabling urine reflux into the syringocele). In 2 patients asymptomatic open syringocele was diagnosed. In 1 patient symptomatic syringocele resolved spontaneously following an infection. In 4 patients open syringocele was treated with transurethral marsupialization because of persistent post-void dribbling. Postoperatively patients were completely symptom-free with a mean followup of 12 months (range 6 to 23). CONCLUSIONS: Cowper's syringocele may be more common than currently realized. Urologists should rule out this possibility in young male patients with lower urinary tract symptoms and persistent post-void dribbling as it can be treated easily.

Staged operative treatment in a septic patient with an infected, unstable pelvis, and a missed bladder rupture.

This case demonstrates once again the potential and serious complications of pelvic fractures, especially when associated urogenital injuries are missed. Missing the bladder rupture proved almost fatal to our patient. Second, it was confirmed that in very unstable pelvic fractures, external fixation alone does not provide enough stability. Local stability is the cornerstone in the treatment of (bone) infection, and in these cases, maximal stability is only obtainable with internal fixation. The advantages of metal implants in infected areas outweigh the disadvantages by far. For the bladder-rupture, we chose a two-stage approach. First, we performed a urinary diversion, to avoid surgical closure of the infiltrated bladder wall. All cavities, including the open bladder, were packed with omentum to fill the dead space with highly vital tissue to offer stout resistance to infection. Two years later, with the patient in excellent physical condition, urinary undiversion was carried out. Ultimately physical and social recovery was complete.
