Background Recurrent prostate cancer after radiotherapy occurs in one in five patients. The efficacy of prostate magnetic resonance imaging (MRI) in recurrent cancer has not been established. Furthermore, high-quality data on new minimally invasive salvage focal ablative treatments are needed. Objective To evaluate the role of prostate MRI in dete...

Background For localised prostate cancer, focal therapy offers an organ-sparing alternative to radical treatments (radiotherapy or prostatectomy). Currently, there is no randomised comparative effectiveness data evaluating cancer control of both strategies. Methods Following the eligibility criteria PSA < 20 ng/mL, Gleason score ≤ 7 and T-stage ≤...

Focal therapy (FT) ablates areas of prostate cancer rather than treating the whole gland. We compared oncological outcomes of FT to radical prostatectomy (RP). Using prospective multicentre databases of 761 FT and 572 RP cases (November/2005-September/2018), patients with PSA < 20 ng/ml, Gleason </= 4 + 3 and stage </= T2c were 1–1 propensity score...

Anejaculation may occur as a result of neurological disease, iatrogenic injury or be drug induced. We report a case of a 66 year old man who presented with anejaculation following an emergency abdominal aortic aneurysm repair. Due to an elevated prostate specific antigen (PSA) level, the patient underwent a prostate biopsy and was diagnosed with a...

Flexible cystoscopy is commonly performed under local anaesthesia. Instillation of lignocaine gel is commonly associated with urethral discomfort, which in some cases results in fierce opposition to further flexible cystoscopy under local anaesthesia. Although studies have demonstrated that the temperature of lignocaine can influence the level of d...

Introduction: A comparative prospective three-arm study was conducted to evaluate the efficacy and safety of interstitial energies (diode laser 830 nm vs. radiofrequency 460 kHz) to produce coagulation necrosis of prostatic adenoma against standard TURP. Patients and methods: From January 1997 to July 1997, 80 patients entered the study (mean age 6...

Introduction: The aim of the study was to evaluate the longterm efficacy of laser ablation of the prostate (using a freebeam technique) and its associated morbidity. Patients and methods: Between November 1992 and November 1995. a prospective study of 170 patients with symptomatic BPH (mean age 64.9 years, range 51-87) was conducted. Before startin...

Introduction: Transurethral needle ablation of the prostate (TUNA) is used to deliver low-level radiofrequency through a catheter device equipped with adjustable needles placed in selected prostatic tissue areas. TUNA ablation produces necrosis by heating tissue to 110 °C. The objectives of this study were to determine the clinical efficacy of TUNA...

A series of 108 renal tumour nephrectomies carried out between 1975 and 1984 was studied to determine the prognostic statistical significance of the relationship between venous involvement and various pathological features. Tumour size, spread, histological grade and lymph node involvement were compared between V0 tumours (58%), V1 (32%) and V2 tum...

The records of 111 patients with multiple superficial grade 1-2 transitional cell tumours of the bladder treated with intravesical Epodyl and followed up for a mean period of 6.4 years were retrospectively analysed. The study showed that 65% of patients responded completely after 12 weekly instillations and 46% of these remained continuously free o...

Intravesical balloon distention was used in 8 patients to stop intractable hemorrhage after radiotherapy for carcinoma of bladder. We recommend this method of treatment only in patients with no evidence of recurrent or residual invasive tumor in the bladder, where the source of bleeding is from superficial submucosal telangiectatic vessels.
Article
Natural history of 'solitary', histological grade 1, stage Ta-T1 transitional cell carcinoma of the bladder was studied in 198 patients retrospectively over a period from 1975 to 1987. Three patterns of tumour behaviour were evident. In 56% of patients the tumour did not recur following the initial resection. Twenty-one percent developed recurrence...

This is a prospective study of first two hundred consecutive cases of TUR-P, computerised and reviewed. So far, not even a single 'open' prostatectomy has been carried out at this centre. Indications for prostatectomy were acute urinary retention (100 patients), chronic urinary retention (9 patients) and disabling prostatic symptoms (91 patients)....

BACKGROUND: Multiparametric magnetic resonance imaging (MRI), with or without targeted biopsy, is an alternative to standard transrectal ultrasonography-guided biopsy for prostate-cancer detection in men with a raised prostate-specific antigen level who have not undergone biopsy. However, comparative evidence is limited. METHODS: In a multicenter, randomized, noninferiority trial, we assigned men with a clinical suspicion of prostate cancer who had not undergone biopsy previously to undergo MRI, with or without targeted biopsy, or standard transrectal ultrasonography-guided biopsy. Men in the MRI-targeted biopsy group underwent a targeted biopsy (without standard biopsy cores) if the MRI was suggestive of prostate cancer; men whose MRI results were not suggestive of prostate cancer were not offered biopsy. Standard biopsy was a 10-to-12-core, transrectal ultrasonography-guided biopsy. The primary outcome was the proportion of men who received a diagnosis of clinically significant cancer. Secondary outcomes included the proportion of men who received a diagnosis of clinically insignificant cancer. RESULTS: A total of 500 men underwent randomization. In the MRI-targeted biopsy group, 71 of 252 men (28%) had MRI results that were not suggestive of prostate cancer, so they did not undergo biopsy. Clinically significant cancer was detected in 95 men (38%) in the MRI-targeted biopsy group, as compared with 64 of 248 (26%) in the standard-biopsy group (adjusted difference, 12 percentage points; 95% confidence interval [CI], 4 to 20; P=0.005). MRI, with or without targeted biopsy, was noninferior to standard biopsy, and the 95% confidence interval indicated the superiority of this strategy over standard biopsy. Fewer men in the MRI-targeted biopsy group than in the standard-biopsy group received a diagnosis of clinically insignificant cancer (adjusted difference, -13 percentage points; 95% CI, -19 to -7; P<0.001). CONCLUSIONS: The use of risk assessment with MRI before biopsy and MRI-targeted biopsy was superior to standard transrectal ultrasonography-guided biopsy in men at clinical risk for prostate cancer who had not undergone biopsy previously.
