Management of pain plays an important role during prostate biopsy. Various types of management of pain plays an important role during prostate biopsy. Various types of anaesthetic methods have been used. The present study aimed to compare the efficacy and complication rate between periprostatic lidocaine infiltration and transrectal lidocaine gel in transrectal ultrasound guided prostate biopsy. All prostate biopsy patients were included except those with lidocaine, allergy, haemorrhagic diathesis, anticoagulation therapy, the inability to rate a visual analogue scale and inability to obtain consent. They were randomized into two groups. Group 1 received 20ml 2% transrectal lidocaine gel. Group 2 received 5ml 1% lidocaine infiltration for each periprostatic nerve block with 23-gauge spinal needle. After three minutes, prostate biopsy was performed with an 18 gauge 7-inch spring-loaded biopsy gun. Six biopsies were taken for each lobe. Pain during probe insertion, biopsy and immediately after the procedure was assessed using the Visual Analogue Scale. Any complication immediately after procedure, one day or after one week, was recorded. Mean pain score was lower after periprostatic lidocaine infiltration compared to transrectal lidocaine gel (3.1 + 1.9 versus 4.9 + 2.4, p = 0.027). There was no statistically significant difference in the complication rate. Transrectal ultrasound prostate biopsy using periprostatic lidocaine infiltration provides better anaesthesia as compared to the transrectal lidocaine gel application with no significant difference in complication. Thus, the use of periprostatic lidocaine infiltration in TRUS guided prostate biopsy is recommended.

Dermoid cyst in a kidney is rarely seen. We report a case of intrarenal dermoid cyst which mimics malignant renal tumour and discuss the dilemma in managing this disease.

Extra-gonadal germ cell tumours (EGGCT) are rare. Therefore further investigations of the testis is aimed at sourcing a possible primary origin of gonadal tumour. Over the years, various case series on EGGCT have been reported questioning its true nature as in a majority of them, a primary source is found in the testis, thus representing a metastatic gonadal tumour. The testis pathology could be either a true germ cell foci, an intra-tubular epithelial neoplasia or an area of fibrosis, indicating a ‘burnt out tumour’. We report a 39-year-old male who underwent laparotomy and excision of a retroperitoneal tumour. Histopathological examination revealed retroperitoneal lymph node of mixed germ cell tumour origin. Clinical and ultrasound examination of bilateral testis was normal. The patient refused orchidectomy or a testicular biopsy. He underwent four cycles of bleomycin, cisplatin, and etoposide with no evidence of tumour recurrence on follow up and remains disease free after 12 months of diagnosis. A literature review of EGGCT, its relation and factors relating with future testicular tumour is presented.

Inflammatory Pseudotumor (IP) of bladder is one of a variety of lesions which may arise from spindle cell lesions in the bladder. It is benign in nature compared to the other end of the spectrum of spindle cell lesions, such as sarcoma, sarcomatoid carcinoma and leiomyosarcoma. The diagnosis of IP and its differentiation from a malignant pathology is a diagnostic dilemma for Urologist and Pathologist as both entities share certain similar morphological and histo-pathological appearance as well as immuno-histo chemistry staining. It is however crucial to avoid misdiagnosis as the treatment option varies significantly between a radical or partial cystectomy with future surveillance cystoscopes. Hereby, we highlight a case of a benign variant of spindle cell tumour of bladder which needed second pathology review for confirmation and thus avoiding a radical cystectomy. We also review the literature on its presentation and emphasis characteristics differentiating a benign from a malignant pathology.

Iatrogenic ureteric injuries are rare complications of
abdomino-pelvic surgery but associated with high morbidity
from infection and possible loss of renal function. A
successful repair is related to the timing of diagnosis, site of injury and method of repair. This study was a retrospective review of outcomes of iatrogenic ureteric injury and factors contributing to successful operative repair. Twenty consecutive cases referred to the Urology Unit of the UKM Medical Center during an 11-year period from 1998 to 2009 were reviewed. Thirteen patients were diagnosed intraoperatively and underwent immediate repair. Seven patients had delayed diagnosis but also underwent immediate repair.
In our series, there was no significant difference in outcome between injuries diagnosed intraoperatively versus injuries with delayed diagnosis. There was significant difference in the outcomes between methods of ureteric repair where ureter reimplantation via psoas hitch or Boari flap yielded better results than primary end-to-end anastomosis Three patients suffered loss of renal function from unsuccessful ureter repair. We conclude that all iatrogenic ureteric injury should be repaired immediately in the absence of overt sepsis. Ureter reimplantation using a Boari flap or psoas hitch is preferred to the end-to-end anastomosis especially when there is delayed diagnosis

Ketamine can be abused as a recreational drug, and there has been a recent surge in its
usage. The effects of ketamine on the urinary system were unknown until the recent publication
of a few case reports. Many doctors are still unaware of this new clinical entity, termed ketamineassociated
ulcerative cystitis. We report a case that we encountered and discuss the diagnosis and
disease management in addition to a review of the literature.

This study aims to determine the prevalence of lower urinary tract symptoms (LUTS) and level of awareness among male outpatients in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A questionnaire consisting of demographic data, questions related to knowledge, attitude and practice on BPH and the International Prostate Symptom Score (IPSS) was used for this study. Uroflowmetry and bladder scan were used to evaluate the function of the urinary tract and severity of BPH. Urine dipstick was done for glycosuria, proteinuria and haematuria. A total of 220 respondents were surveyed. The prevalence of moderately and severely symptomatic LUTS was 42.7%. The most commonly reported LUTS were nocturia (78.2%), frequency (58.2%) and incomplete emptying (44.6%). The prevalence of glycosuria, proteinuria and haematuria were 23.6%, 11.4% and 1.8% respectively. There was a significant association between increasing age with the severity of LUTS (p=0.005). Out of 102 respondents with voided urine volume greater than 150 mL, there was a significant decrease in maximum (Qmax) (p=0.039) and average (Qave) urine flow rates with every 10 years increase of age (p=0.001). The majority of respondents (59.5%) have heard of BPH before. Over 78.2% of the respondents would seek medical attention if they have LUTS with 15.9% saying they would seek traditional treatment. In conclusion, the prevalence of LUTS was high and the level of awareness was satisfactory.
