RESUMO
OBJECTIVES: To assess the efficacy of incision and venous patch grafting method in the surgical treatment of the curvature in Peyronie's disease. METHODS: Fifty-eight patients with Peyronie's disease underwent incision of the tunica albuginea with Peyronie's plaque(s) and venous patch grafting between 1994 and 1999. Segment(s) of lower saphenous vein in 48, deep dorsal vein in 7, and upper saphenous veins were used in 3 cases as venous patch(es). Assessment of the potency status, curvature, and vascular structure were performed pre-operatively with detailed history, counselling, autophotography, and color Doppler ultrasonography. Realistic expectations from the surgery was discussed with the patients in advance. Postoperative evaluation was performed at least twice, in the 6th week and the 3rd month. The third evaluation was done in 12-36 months by telephone. RESULTS: Fifty of the patients (86%) achieved straight erections after the surgery. Five patients (9%) had improvement in their penile curvature that enabled them to perform sexual intercourse easily. In 3 of our patient (5%) recurrence of the curvature was observed. Penile shortening of 0.5-1.5 cm was observed in 13 of the cases (22.4%). Fifty-four cases (93%) reported no change in their quality of erections. CONCLUSION: Incision of the tunica albuginea and venous patch grafting technique is a very satisfactory surgical method in the treatment of the curvature in Peyronie's disease.

PURPOSE: We assess the efficacy of extracorporeal shock wave lithotripsy monotherapy for isolated lower pole nephrolithiasis, and compare it to that for isolated middle and upper caliceal calculi. MATERIALS AND METHODS: We treated 714 renal units in 687 patients with isolated caliceal stones using a Lithostar lithotriptor (Siemens Medical Systems, Erlangen, Germany). The stones were localized in the lower, mid and upper calices in 455, 104 and 128 patients, respectively. Stone load was recorded in cm.2. Patients were stratified into 3 groups based on stone burden. The energy and shock waves, use of anesthesia, number of treatment sessions, auxiliary measures and complications were noted. Patients were evaluated with intravenous urogram or plain film of kidneys, ureters and bladder, and ultrasonography when stone-free, or clinically significant residual fragment status, including nonobstructive and noninfectious insignificant fragments 4 mm. or less, was noted at the fluoroscopic control 2 to 4 weeks after the last session. Final clinically significant residual fragment decision was made 10 to 12 weeks after the last session. Extracorporeal shock wave lithotripsy was considered a failure if no fragmentation was noted after session 3 and continued if fragmentation was noted. Results regarding caliceal localization were compared. RESULTS: Complete data were available on 591 renal units. Auxiliary procedures were used in 81 (14%) units before treatment. Anesthesia was given to 101 (17%) patients. The mean number of shock waves and energy used were 2,022 and 17.4 kV., respectively. The difference in shock wave, energy and treatment rate among 3 caliceal locations reached statistical significance only for energy delivered to the lower and upper calices. The effectiveness quotient of extracorporeal shock wave lithotripsy was 36%, 46% and 41% for lower, middle and upper pole stone disease, respectively (p = 0.4). There was a highly significant correlation between stone-free and re-treatment rates, and stone burden. The overall stone-free rate was 66%, and 63%, 73% and 71% for lower, middle and upper caliceal stones, respectively (p = 0.1). For the group with stones greater than 2 cm.2 overall stone-free rate decreased to 49%, and 53%, 60% and 23% in lower, middle and upper caliceal locations, respectively. Overall, extracorporeal shock wave lithotripsy monotherapy failed in 46 (7.7%) renal units. Steinstrasse developed in 39 (6.5%) patients who were then treated with repeat lithotripsy. CONCLUSIONS: Extracorporeal shock wave lithotripsy appears to be successful for management of isolated caliceal stone disease. Treatment efficacy was not significantly different among stones localized in lower, middle and upper poles. We recommend it as the primary treatment of choice for stones less than 2.0 cm.2 in all caliceal locations. Treatment should be individualized for management of caliceal stones greater than 2.0 cm.2 until large prospective randomized trials comparing shock wave lithotripsy and percutaneous nephrolithotomy are available.

PURPOSE: We reviewed our experience with SWL for stones in abnormal urinary tracts and compared the results with those in normal urinary tracts. PATIENTS AND METHODS: The study group was composed of 2566 renal units (RU) treated on the Siemens Lithostar lithotripter at our SWL unit whose treatment and follow-up at 10 to 12 weeks were completed. Sixty-eight RUs (2.7%) belonged to 52 patients who had congenital upper urinary tract abnormalities. Logistic regression analysis was performed to analyze the impact of age, stone size, location, and the type of abnormality on the outcome of the SWL in the abnormal RU. The student t-, chi-square, and Fisher's exact tests were used for the comparison of stone load, number of treatment sessions, catheter placement, and success rates of the patients with normal and abnormal RU. Results of long-term follow-up for available patients (38 RU; 56%) were also evaluated. RESULTS: Age, stone load, stone location, and the type of abnormality did not have a statistically significant impact on the outcome of SWL for abnormal RU. The average stone load was 2.1 +/- 2.8 cm2 in the abnormal and 1.4 +/- 1.3 cm2 in the normal RU. Thus, the stone load was significantly higher in the abnormal RU (P < 0.05). In the abnormal group, 56% of the RU became stone free, 37% had nonobstructive and noninfectious clinically insignificant residual fragments < or = 4 mm (CIRF), and SWL failed in 7%. In the normal group, 78% of the RU became stone-free, 18.5% had CIRF, and SWL failed in 4%. There was no significant difference in the success rates in the groups if success was defined as stone free and CIRF together (P > 0.05). However, there was significant a difference when stone-free, CIRF, and failure rates were evaluated separately (P < 0.05). Recurrence, regrowth, and retreatment rates in abnormal RU were 50%, 37%, and 34%, respectively. CONCLUSIONS: Although the fragmentation rates were similar, clearance of the fragments was hampered in abnormal urinary tracts. Thus, especially for large stones, other endourologic treatment options should be considered. High recurrence and regrowth rates warrant careful monitoring and consideration for medical treatment during follow-up.

We report a case of a 49-year-old man who presented with symptoms related to his right eye. Subsequent workup revealed carcinoma of the prostate metastatic to the uvea. On ophthalmologic evaluation, choroidal metastasis was noted. His prostate was firm on digital rectal examination, and the serum prostate-specific antigen level was 124 ng/mL. Prostate biopsy was consistent with adenocarcinoma, Gleason score 9. The patient was treated with total androgen blockade and radiation to the eye. Although his ocular lesions disappeared, the patient died of hormone-refractory disease 32 months after the diagnosis. The first case of prostate cancer metastatic to the uvea was reported more than 1 century ago; however, only a few cases have been reported subsequently. To our knowledge, we present the first published report in the urological literature of a patient in whom ocular complaints were the presenting symptoms that led to the diagnosis of prostate cancer. The urologist should be cognizant of the distinct possibility of ocular metastasis if a patient with prostate cancer presents with complaints related to the eye.

OBJECTIVE: The complications of the sigma rectum pouch were analyzed. METHODS: A total of 60 patients who underwent a construction of the Mainz pouch II was analyzed retrospectively. Data on early complications was available for all patients, while long-term follow-up data was available for 50 patients. RESULTS: Perioperative mortality was nil. Early complications were encountered in 2 (3.3%) patients. Oral alkalizing supplementation therapy was required in 30 (60%) of the patients; 3 (6%) patients needed hospitalization for severe acidosis and hypokalemia. Hydronephrosis developed in 5 (5%) of 98 renoureteral units anastomosed. Acute pyelonephritis was observed in 3 (8%) patients. All of the patients were continent except for 1 female patient who had had previous radiotherapy to the pelvis. The mean voiding frequency during the day and night was 5.1+/-1.1 and 1.9+/-0.7, respectively. The psychological state and general health of 2 patients became progressively worse until they died of probable malnutrition and metabolic abnormalities. Mechanical bowel obstruction developed in 1 patient 2 years after surgery. CONCLUSION: The complication rate of the Mainz pouch II appears to be acceptable with a median follow-up of 31 months. Patient selection and cooperation are of paramount importance for a successful outcome.

Ten to twenty percent of paragangliomas occur at extra-adrenal locations and less than 1% are at the urinary bladder. The most common presenting symptom of bladder paraganglioma is hypertensive attacks precipitated by micturition and hematuria. Paraganglioma of the urinary bladder occurring at pregnancy is extremely rare. We present a case of bladder paraganglioma as an unusual cause of early preeclampsia. After termination of the pregnancy, surgical resection was performed and the histopathologic diagnosis of paraganglioma confirmed. At 24 months of follow-up the patient felt well and was normotensive without any foci of paraganglioma. Although rare, paraganglioma must be considered in the differential diagnosis of early preeclampsia.

BACKGROUND: We aimed to determine the long-term results of Burch colposuspension. METHODS: Patients who had undergone Burch colposuspension due to stress urinary incontinence (SUI) in our department between 1991 and 1995 were asked to participate in the study by telephone or mail. Fifty of 78 patients (64%) responded and these formed the study group. Patients were evaluated by a detailed questionnaire, pelvic examination, uroflowmetry and postvoid residual urine determination. Provocative stress test and urodynamic evaluations were performed in those who claimed leakage. Additionally, follow-up charts were retrospectively reviewed from the patients' files. RESULTS: Mean follow-up time was 50.6 months. The subjective cure rate was 52% and the surgical success rate was 84%. The patient satisfaction rate in terms of incontinence was 86%. No correlation was found between pre-operative patient characteristics (i.e. age, number of vaginal deliveries and pregnancies, menopause, previous anti-incontinence surgery and presence of detrusor instability) and outcome of surgery. Although no patient was performing clean intermittent catheterization in the long term, two patients had significant residual urine and obstructive flows. Three patients had severe pelvic prolapse that required surgical correction. CONCLUSIONS: Our results indicate that Burch colposuspension operation is an effective and durable choice of treatment with low complication rates for the treatment of SUI.

OBJECTIVES: To present our reconstructive surgery experience with voiding dysfunction due to both neurologic and non-neurologic etiology. METHODS: From March 1993 to January 2000, 69 patients (43 men and 26 women) with voiding dysfunction underwent lower urinary tract reconstruction. Mean patient age at the time of surgery was 34. 5 years (range 9 to 75). Voiding dysfunction had a neurologic etiology in 65.2% of the patients and a non-neurologic etiology in 34.8%. Urodynamic investigation revealed poor bladder compliance in 52%, detrusor hyperreflexia in 19%, and a combination of the two in 29% of the patients. Thirteen patients (19%) had coexistent intrinsic sphincteric deficiency. A total of 56.5% of the patients had upper urinary tract deterioration. Most patients (78%) had severe urinary incontinence. Augmentation cystoplasty was performed in 60 patients. Nine patients had augmentation cystoplasty with a continent stoma. Concomitant procedures were performed in 11 patients. RESULTS: Mean follow-up was 36.6 months (range 8 to 108). Marked improvement of the upper tracts was documented in 79% of the patients in the neuropathic and 73% in the non-neuropathic group. High continence rates were achieved in both groups (82% and 94%, respectively). Intermittent catheterization rate was 88.6% in the neuropathic and 44% in the non-neuropathic groups and patient satisfaction rate was 84% and 94%, respectively. Three major complications in 2 patients required surgery. CONCLUSIONS: Surgical reconstruction to treat urinary incontinence and upper urinary tract deterioration gives satisfactory results in voiding dysfunction in the case of medical treatment failure.

A case of retrovesical leiomyosarcoma in a male patient is described. The preoperative radiological and laboratory studies were inconclusive in determining the primary origin of the tumor. Diagnosis of a malignant tumor with smooth muscle origin was suggested by needle biopsy. However, the definitive diagnosis and the primary site of origin could only be determined by surgical exploration and subsequent histopathologic examination after excision. No sign of recurrence or metastasis was present 12 months after complete surgical resection.

We describe the application of a retubularized ileal stoma (Monti procedure) to an ileocecal pouch in a patient with a spinal cord injury who required a continent urinary diversion. When constructing a continent diversion with an ileocecal pouch, this technique seems a good choice, with significant advantages over the other alternatives.

BACKGROUND: Shockwave lithotripsy (SWL) is being used increasingly as a therapeutic modality for childhood urolithiasis. We reported our experience and results of SWL in the pediatric population. METHODS: The 59 renal units (RU) of 54 patients were retrospectively reviewed. The mean patient age was 10+/-3.5 years. All patients were treated with the Lithostar lithotripter in outpatient settings. Those with positive culture results were treated under appropriate antibiotic coverage. Seven patients were treated under general anesthesia and the rest under sedoanalgesia. Shielding of the lung fields or gonads was not used. For the upper pole stones, protection of the lungs was accomplished by elevating the upper half of the body with supportive pillows, thus moving the kidney away from the lung fields. Six RUs were catheterized via double-pigtail ureteral catheters or by percutaneous nephrostomy tube prior to treatment. The average stone load was 1.8+/-2.5 cm2. RESULTS: Patients were treated with an average of 2.5 sessions. A total of 1000 to 2500 shockwaves were delivered between 14.5 and 17.8 kV. Routine spasmolytic treatment was not initiated. The stone-free rate was 64%, and clinically insignificant residual fragments (CIRF) were present in 29% of RUs; thus, the success rate was 93%. Fever that necessitated hospitalization occurred in one patient. No other complications were seen except skin bruising and early hematuria. CONCLUSION: Shockwave lithotripsy is a safe and effective treatment modality for childhood stones of appropriate size and radiologic characteristics.

PURPOSE: We report our clinical experience with Behçet's syndrome and bladder involvement. MATERIALS AND METHODS: From April 1991 through July 1996, 7 men and 1 woman 25 to 53 years old with Behçet's syndrome were evaluated for lower urinary tract symptoms (7) or hematuria (1). Of 8 patients 5 had neurological involvement. Evaluation consisted of history, physical examination, urinalysis and urine culture, excretory urography, urodynamic studies, urethrocystoscopy, bladder biopsies and histopathological examination. RESULTS: Cystoscopy revealed bladder ulcer in 1 patient and an indurated, hypervascular lesion in another with bilateral hydronephrosis. The most common urodynamic finding was detrusor overactivity. Of 4 patients with poor compliance 1 had additional sphincteric deficiency. Common histopathological features were moderate and marked thickening of bladder vessel walls. Lymphocytic vascular reaction was present in 2 patients and lymphocytic vasculitis in 1. Clamshell augmentation ileocystoplasty was performed in 3 patients, including 1 who also underwent a sphincter enhancement procedure. The remaining 5 patients received various nonsurgical treatment. CONCLUSIONS: Various types of voiding dysfunction relating to bladder and sphincteric components in both phases of micturition can be seen in Behçet's syndrome. Voiding dysfunction can be due to either neurological or direct bladder involvement. Augmentation ileocystoplasty is a good treatment option for Behçet's syndrome with severe bladder involvement.

The cut-off value of serum prostate-specific antigen (PSA) level in prediction of bone metastases and the correlation of serum PSA with the clinical stage, grade, score and the rate of bone metastases have been investigated in cases of prostate cancer (PCa). The study population consisted of 160 patients with histologically proven PCa between April, 1993 and August, 1996. The negative predictive value and the sensitivity were the highest (94%) in patients with a serum PSA value less than 10 ng/ml. We claim that in patients with PSA values less than 10 ng/ml whole body bone scan is not necessary.

OBJECTIVES: To establish the urologic status of men with Behcet's syndrome, because studies assessing the urologic aspect of Behçet's syndrome are rare. METHODS: During a 2.5-year period, we evaluated 104 male patients with Behçet's syndrome, 16 to 50 years old (mean 31+/-7), using a urologic questionnaire and modified Boyarsky symptom score; 44 healthy men, 20 to 46 years old (mean 29+/-7), were used as control subjects. RESULTS: The frequency of epididymitis in patients with Behçet's syndrome was 19.2% in this study. The mean irritative symptom score was 1.22+/-1.37 (significantly higher than the control group). The frequency of lower urinary tract symptoms (eg, dysuria, urgency, nocturia, terminal dribbling, and intermittency) was significantly higher in patients with Behcet's syndrome. CONCLUSIONS: In this study, the frequency of epididymitis in men with Behcet's syndrome was much higher than previously reported. Because some lower urinary tract symptoms were significantly more frequent in these patients, we conclude that screening of such patients with urologic questionnaire and symptom scoring is essential to identify those who need further urologic evaluation.

OBJECTIVE: To analyze the impact of 2 systematic transition zone (TZ) biopsies in addition to systematic sextant biopsies in an effort to establish the importance of cancer detected in the transition zone. METHODS: Between November 1995 and October 1996, TRUS-guided systematic sextant peripheral zone (PZ) and two additional TZ biopsies were performed on 189 consecutive men. Radical retropubic prostatectomy (RRP) was performed to 13 patients with organ-confined prostate cancer. The biopsy results of the 52 patients with cancer and the pathological specimens of the patients who underwent surgery were compared. RESULTS: Of the 189 patients, 52 (27.5%) had prostate cancer of whom 20 (38.5%) both in the PZ and TZ, 31 (59.6%) only in the PZ, and 1 (1.9%) in the TZ only. Of the 96 patients with high serum PSA levels despite normal DRE, 14 had prostate cancer. TZ cancer only rate was 7.1% (1 in 14 patients) in this group. RRP was performed to 8 patients who had cancer only in the PZ and 5 patients in both TZ and PZ. The pathological stages of the postoperative specimens and extracapsular extension rates of those with cancer in the PZ and TZ were significantly higher (p = 0.029 and p = 0.008, respectively). CONCLUSIONS: Routine TZ biopsy does not substantially increase the prostate cancer detection rate, however it can be useful in selected patient groups. If further studies reveal the relationship of cancer in the transition zone, higher capsular extension rate (pT3 cancer) and higher pathological stage after radical surgery, then TZ biopsies may yield additional information that might influence the therapeutic approach.

Nephroureterectomy is the standard surgical approach for upper urinary tract transitional-cell carcinoma (TCC) and many other conditions. In 1952, a modification of the conventional method was described in which a transurethral resection of the ureteral meatus and intramural ureter is undertaken until the remaining ureter has no attachment to the bladder. The resected area and the distal tip of the ureter are coagulated, and the ureter is removed in continuity with the kidney through a single flank incision. Since January 1990, we have performed 12 nephroureterectomies with this technique (9 men and 3 women with an average age of 61.8 years, ranging from 35 to 73). Six of them were operated on for a TCC of the upper urinary tract, and the postoperative follow-up of these patients was from 6 to 54 months (mean 18.6). Within the follow-up period, tumor has not recurred either at the resected trigonal area or in the retroperitoneum, and only one patient has had a tumor distant from the site of ureteric resection. One patient with bladder TCC, who had a suspect kidney mass on the left side detected by CT, underwent nephroureterectomy with this technique. Five patients had primary renal disorders and upper tract calculous problems, in which nephroureterectomy was required. After the transurethral resection, an indwelling catheter was left in the bladder for 4 days. We believe that our experience confirms the feasibility of this technique in order to improve and simplify nephroureterectomy. Therefore, we recommend the modified "pluck" technique in all patients who are candidates for an operation requiring nephroureterectomy, as it gives considerable benefit to the patient.

OBJECTIVE: To investigate correlations between traditional and urodynamic criteria in the evaluation of prostatism and to try to establish an update evaluation of patients with benign prostatic hyperplasia (BPH) with the aim of preventing unnecessary prostatectomies. PATIENTS AND METHODS: The series constituted 96 patients aged 43-86 years (mean 63.41 +/- 9.25) with prostatism and BPH. All were assessed by symptom analysis, digital rectal examination, residual urine determination, uroflowmetry and further multichannel urodynamic testing (medium fill cystometry, pressure flow study). RESULTS: Residual urine determination was not a reliable criterion for selection of patients for surgery. A striking statistically significant correlation was evident when symptomatology and the results from multichannel urodynamic study were compared. No correlation was found between irritative symptoms and detrusor instability. CONCLUSION: A significant proportion (23%) of the whole patient population was classified as a urodynamically unobstructed group to which we think prostatectomy should not be offered. We recommend that a pressure-flow study is performed in all patients with BPH with dominant irritative symptoms to identify those who are unobstructed.

There are conflicting reports about the natural history and prognosis of bladder tumours in patients under 40 years of age. A review of 156 patients younger than 40 treated at our Department between 1960 and 1991 with transitional cell carcinoma of the bladder revealed that 89.1% had superficial (Ta/T1) disease and the remaining 10.9% presented with invasive disease. Slightly more than half of the patients with superficial disease had multiple tumours. The follow-up of 97 patients over a period of 12-372 months revealed that there was a recurrence rate of 10.3% and 38.4% for Ta and T1 tumours, respectively (p < 0.01). Further analysis comparing patients under 30 to those between 30 and 40 years revealed recurrence rates of 7.5% and 22%, respectively (p < 0.05). Progression rates for Ta and T1 tumours are 3.5% and 19.3% (p < 0.05). In the invasive disease group 8 patients were lost for follow-up, 2 died of the disease and the remaining 7 are alive, with a mean follow-up of 3.6 years. We conclude that while transitional cell carcinoma of the bladder in patients under 30 behave less aggressively, the behaviour of the disease in patients 30 to 40 years old is similar to the older age group and should be monitored closely, especially when risk factors for recurrence and progression are present.
