Double-J stent insertion across vesicoureteral junction--is it a valuable initial approach in neonates and infants with severe primary nonrefluxing m…
2006
Abstract Objectives To evaluate the role of double- J stent insertion in perinatally detected primary nonrefluxing megaureters as a method to temporize treatment in patients with impaired renal function or to prevent function loss in patients treated expectantly, but deemed at high risk of deterioration. Methods Two neonates and 8 infants with a ureter greater than 10 mm and an obstructive excretion pattern, including 3 cases with renal function less than 40%, were selected to undergo double- J stent insertion for a 6-month period. Patients underwent surgery if the ureter redilated and the excretion pattern was obstructive at reassessment 3 months after stent removal. Results Stents were pl…
The pathologist's role in the detection of rare variants of bladder cancer and analysis of the impact on incidence and type detection.
2018
BACKGROUND: Histology is one of the most important factors determining the prognosis of bladder cancers and rare variants are generally associated with decreased disease specific survival compared to pure transitional cell carcinomas. We believe that rare bladder cancer variants are likely underdiagnosed in the absence of a dedicated uro-pathologist in many centers. The objective of this study is to evaluate the contribution of a dedicated uro-pathologist on the identification of rare bladder cancer variants. METHODS: We retrospectively analyzed the clinical and histological records of all patients which underwent a radical cystectomy and lymph node dissection between January 2000 and Septe…
Kelfiprim, a new sulpha-trimethoprim combination, versus cotrimoxazole, in the treatment of urinary tract infections: a multicentre, double-blind tri…
1982
A new combination of trimethoprim with a sulphonamide, named Kelfiprim, differs from cotrimoxazole in that: a) the sulpha drug is sulphamethopyrazine instead of sulphamethoxazole; b) the trimethoprim to sulpha ratio is 5:4 instead of 1:5;c) the presence of a long-acting sulphonamide allows the administration of a daily dose of one capsule, following an initial loading dose of two capsules; d) a reduced amount of trimethoprim is given, as compared to cotrimoxazole, without any decrease of efficacy. Kelfiprim [KP] was compared to contrimoxazole [Co] in a multicentre double blind trial. Sixty four patients suffering from acute and chronic infections of the upper and lower urinary tract entered…
The effect of intracavernosal growth differentiation factor-5 therapy in a rat model of cavernosal nerve injury.
2006
OBJECTIVE To determine whether the intracavernosal application of growth differentiation factor-5 (GDF-5) influences nerve regeneration and erectile function after cavernosal nerve injury in a rat model. MATERIALS AND METHODS Thirty-two male Sprague-Dawley rats were randomly divided into four equal groups: eight had a sham operation (uninjured controls), while 24 had bilateral cavernosal nerve crush. The crush-injury groups were treated at the time of injury with an impregnated collagen sponge implanted into the right corpus cavernosum. The sponge contained no GDF-5 (injured controls), 2 µg (low concentration), or 20 µg GDF-5 (high concentration). Erectile function was assessed by cavernosa…
Huge isolated port-site recurrence after laparoscopic partial nephrectomy: a case report.
2009
A 66-yr-old man with pain and swelling in the right flank was referred to our clinic for diagnosis. In 2005, the patient underwent a laparoscopic partial nephrectomy for renal cancer of the lower pole of the right kidney. A computed tomography scan revealed a 20-cm tumor in the right abdominal wall, resulting in a suspected diagnosis of port-site metastasis from the first laparoscopic operation. The patient underwent open surgery, which confirmed the diagnosis. After the operation, the patient recovered rapidly.
Renal tumour surgery in elderly patients.
2008
OBJECTIVE To analyse morbidity, renal function and oncological outcome in patients aged ≥80 years who had surgery for renal tumours, as in the elderly such surgery is controversial in relation to life-expectancy and other causes of death. PATIENTS AND METHODS Between 1990 and 2006, in our institution 1625 patients had surgery to treat solid renal tumours suspected to be renal cell carcinoma (RCC); 62 (4%) were aged ≥80 years (mean 82.5), and 73% of these elderly patients had radical nephrectomy (RN) and 27% nephron-sparing surgery (NSS). Results The median (range) follow-up was 3.1 (0.2–14.1) years (89% of the patients). There was no perioperative mortality. There were only minor complicati…

Predictors of oncological outcomes in T1G3 patients treated with BCG who undergo radical cystectomy
2018
PURPOSE: To evaluate the oncological impact of postponing radical cystectomy (RC) to allow further conservative therapies prior to progression in a large multicentre retrospective cohort of T1-HG/G3 patients initially treated with BCG. METHODS: According to the time of RC, the population was divided into 3 groups: patients who did not progress to muscle-invasive disease, patients who progressed before radical cystectomy and patients who experienced progression at the time of radical cystectomy. Clinical and pathological outcomes were compared across the three groups. RESULTS: Of 2451 patients, 509 (20.8%) underwent RC. Patients with tumors > 3 cm or with CIS had earlier cystectomies (HR = 1…
Recurrence, progression and cancer-specific mortality according to stage at re-TUR in T1G3 bladder cancer patients treated with BCG: not as bad as pr…
2018
PURPOSE: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis to adequately stage and treat the patient. Persistent disease after TUR is not uncommon and is why re-TUR is recommended in T1G3 patients. When there is T1 tumor in the re-TUR specimen, very high risks of progression (82%) have been reported. We analyze the risks of recurrence, progression to muscle-invasive disease and cancer-specific mortality (CSM) according to tumor stage at re-TUR in T1G3 patients treated with BCG. METHODS: In our retrospective cohort of 2451 T1G3 patients, 934 patients (38.1%) underwent re-TUR. 667 patients had residual disease (7…
