Radical cystectomy with W-shaped orthotopic ileal neobladder constructed with non-absorbable titanium staples-long term follow-up.

PURPOSES: We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non-absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications. MATERIALS AND METHODS: We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W-configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually. RESULTS: Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year. CONCLUSIONS: The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients.

7 to 10 years' follow-up of 573 patients with elevated prostate-specific antigen (>4 ng/mL) or/and suspected rectal examination: biopsies protocol and follow-up guides.

PURPOSE: In this study, we tried to design a scheme for performing transrectal ultrasonographic (TRUS)-biopsies that would be accurate and include the optimal number of cores. PATIENTS AND METHODS: We included in this study 600 consecutive patients with suspicious findings on a per-rectum examination and/or an elevated prostate-specific antigen (PSA) (>4 ng/mL) level. Patients were followed for 7 to 10 years. In all patients, we took from 8 to 16 biopsy samples, according to the prostate volume, from the lateral aspects. In the second session, the biopsy samples were taken medially; in the third session, we included the transitional zone, while in consecutive sessions, we increased the number of cores from all areas. RESULTS: Only 573 of the patients remained in follow-up. TRUS-biopsy detected prostate cancer (PCa) in 257 patients (44.85% overall detection rate). The detection rate in the first and second sessions was 32.98% and 14.94%, respectively, reaching 13.2% and 2.17%, in the third and fourth sessions, respectively. Prostate volumes were significantly smaller (52.9 +/- 22.4 cc vs 58.9 +/- 23.8 cc, P < 0.002) and the PSA/adenoma/prostate volumes ratio (ad-pro) ratio was higher (18.3 +/- 9 vs 13.96, P < 0/001) in the patients with PCa. Patients with PCa underwent fewer biopsy procedures and biopsy sessions than patients without a diagnosis of PCa (14.9 +/- 8.9 vs 20.4 +/- 12, P < 0.001;1.3 +/- 0.6 vs 1.7 +/- 0.9, P < 0.001). Biopsy samples obtained from the base were positive for cancer only in larger prostates with a mean volume of 54.3 +/- 15.3 cc. Numbers of biopsy procedures and PSA/ad-pro ratio were the strongest predictive factors for PCa detection (P < 0.001). CONCLUSIONS: In patients with a prostate volume >or=53 cc and PSA/ad-pro ratio >or=18, the optimal biopsy cores should be >or=15. Using this scheme, the discontinuation of biopsy procedures might be considered after three consecutive sessions.

Non-contrast computerized tomography (NCCT) and dynamic renal scintigraphy (DRS) in the patients with refractory renal colic.

OBJECTIVES: To assess the importance of combined use of non-contrast computerized tomography (NCCT) and dynamic renal scintigraphy (DRS) in evaluation of patients with refractory flank pain in the emergency department. METHODS: The study involved 64 consecutive patients with refractory renal colic. All patients were evaluated with plain abdominal films kidneys, ureters and bladder (KUB), NCCT and DRS. We assessed the accuracy of different diagnostic procedures and their combinations; in addition, we determined their importance for different steps of evaluation. RESULTS: Urololithiasis was diagnosed in 76.6% (n=49) of the patients. Twenty-nine percent of calculi were > 4 mm. Surgical intervention were performed in 20 patients (40.8%). A combination of NCCT plus DRS yielded the greatest sensitivity (96%) in establishing final diagnosis, however clinical, laboratory and KUB data in combination with DRS, yielded greater specificity (93%) and PPV (97%). Sex (male), WBC (mean 10.2 x 10(3) +/- 3.1) and KUB (calculus > 4 mm) were chosen in the three-step multi-variant analysis, while only male sex was found to be the strongest predictor (p<0.056) of necessity to perform NCCT. In making decision for definitive treatment NCCT and DRS provided the most important information about stone size and obstruction (kappa=0.734, p<0.001 and kappa=0.625, p<0.001), while DRS was selected as the most important diagnostic procedure in the emergency department (kappa=0.527, p<0.001). CONCLUSIONS: In the emergency department, DRS combined with the results of clinical investigation may indicate candidates for hospitalization with emergency intervention. Immediate NCCT must be strongly considered in men with WBC> or =10 x 10(3) and calculi > 4 mm on the KUB.

Emergency extracorporeal shockwave lithotripsy for acute renal colic caused by upper urinary-tract stones.

PURPOSE: To evaluate emergency SWL for the treatment of upper urinary-tract stones causing renal colic. PATIENTS AND METHODS: Between January 1999 and June 2003, 53 patients with a mean age of 46.6 years (range 22-65 years) were enrolled. The inclusion criteria were acute renal colic, radiopaque 5-mm to 1.5-cm calculi in the ureteropelvic junction (N=10) or upper ureter (N=43), and no evidence of urinary-tract infection or acute renal failure. The mean stone size was 7.14 mm (range 5-13 mm). Patients were randomly assigned to the control (N=28) and study (N=25) groups using previously prepared cards in envelopes. Patients in the study group underwent emergency SWL, while patients in the control group underwent scheduled SWL within 30 days. Stone status was evaluated 4 weeks after lithotripsy. There was no significant difference between the control and study groups with respect to age, sex, stone location or volume, renal obstruction, or days spent in the hospital for pain control. Available fragments of stones were sent for infrared spectroscopy. Preoperative and postoperative data were compared in the two groups using SPSS 10.0 statistical software. RESULTS: The SWL treatment lasted 50+/-11 minutes. The stone-free rates were 72% and 64% and the efficiency quotients were 53% and 44% in study and control groups, respectively. Patients in the control group spent more time in the hospital (P=0.014) and in recovery at home (P=0.011). CONCLUSION: Emergency SWL for acute renal colic caused by upper-ureteral stones is a safe procedure and offers effective release from pain and obstruction. It also decreases hospitalization days and hastens return to normal activity.
