Open partial nephrectomy for a collision renal cell carcinoma in a transplant kidney: A case report.

A collision tumour of the kidney is a very rare condition defined by two immediately adjacent but histologically distinct neoplasms that coexist within one organ without histological admixture. We present a collision tumour in a transplant kidney treated with open partial nephrectomy. This case also highlights key surgical principles the enhanced risk of oncogenesis in transplant recipients, and some key principles for surgical resection of a tumour in a transplant kidney.

Delays in the diagnosis and initial treatment of bladder cancer in Western Australia.

OBJECTIVES: To quantify and examine the causes of delays in the diagnosis and initial treatment of patients with bladder cancer in Western Australia. SUBJECTS AND METHODS: All attendances at a one-stop haematuria clinic at a public tertiary-level hospital in Western Australia between May 2008 and April 2014 were reviewed retrospectively. All patients diagnosed with a bladder tumour over this period were identified. These patients and their general practitioners were contacted retrospectively and invited to participate in telephone interviews, with additional data collected from clinical records as required. Waiting times to presentation, referral, assessment, and initial treatment were established for patients who presented with visible haematuria. RESULTS: Of 1 365 attendances, 151 patients were diagnosed with a bladder tumour and 100 of these were both suitable and agreed to participate in the study. For patients with visible haematuria the median (range) waiting time from initial bleeding to surgery was 69.5 (9-1 165) days. This was comprised of a median (range) pre-referral waiting time of 12 (0-1 137) days, assessment waiting time of 23.5 (0-207) days, and treatment waiting time of 20 (1-69) days. Reasons for prolonged waiting times included poor public awareness, patient fear and anxiety, delayed and non-referral from primary care, administrative delays, and resource limitations. CONCLUSION: Many patients experience significant delays in the diagnosis and treatment of their bladder cancer in Western Australia, and this probably reflects national trends. These concerning data warrant consideration of how delays can be reduced to improve outcomes for these patients.

The case of the shrinking testis.

We report the case of a man with idiopathic lymphocytic orchitis (LO) manifested by undifferentiated testicular pain and atrophy. Conventional investigation results were unremarkable. Oral ciprofloxacin only improved the pain temporarily. Scrotal exploration surgery was performed to exclude acute testicular torsion and a biopsy was taken during surgery for histological examination. Histology revealed severe LO with reduced spermatogenesis. A trial of oral steroids was initially effective but the effect was temporary. Due to chronic pain, he eventually underwent unilateral orchidectomy. Histology confirmed the initial diagnosis of LO. He was pain-free postoperatively. Idiopathic LO is a rarely reported cause of testicular atrophy.

First report of the stapled mesh stoma reinforcement technique in a urologic context.

Parastomal hernia is a common complication of ileal conduit formation. Mesh repair of parastomal hernia has lower rate of recurrence than nonmesh techniques but can be time-consuming to perform. The stapled mesh stoma reinforcement technique (SMART) is a novel method of rapidly constructing a reinforced stapled stoma. We report the first case utilising this technique in a urologic context. The procedure was performed on a middle-aged female with recurrent parastomal hernia of her ileal conduit. There were no perioperative complications. The resited stoma remained healthy and functioned normally. Longer term data is clearly desirable though this technique deserves consideration in the treatment of urologic parastomal hernias. This case demonstrates that SMART is an easy and convenient procedure for parastomal hernia repair.

The conservative management of renal trauma: a literature review and practical clinical guideline from Australia and New Zealand.

OBJECTIVE: To review the literature and make practical recommendations regarding the conservative management of renal trauma. PATIENTS AND METHODS: Relevant articles and guidelines published between 1980 and 2014 were reviewed. Graded recommendations were constructed by a multi-disciplinary panel consisting of urologists, radiologists, and infectious disease physicians. These recommendations underwent formal review and debate at the Western Australian USANZ 2013 state conference, and were presented at the USANZ 2014 annual scientific meeting. RESULTS: The literature on the conservative management of renal trauma is reviewed within the framework of the American Association for the Surgery of Trauma (AAST) kidney injury severity scale. Graded recommendations are made regarding several key topics including: imaging, inpatient management, antibiotics, return to activity, and follow-up. Grade IV injuries and intraoperative consults are examined separately in view of the difficulties these groups cause in making appropriate treatment decisions. CONCLUSION: A practical clinical guideline is provided regarding the conservative management of renal trauma.

Coronary catheterisation does not lead to retinal artery emboli in short-term follow-up of cardiac patients.

BACKGROUND AND PURPOSE: There is emerging evidence that coronary catheterization can cause cerebrovascular embolization. We aimed to assess the proportion of cardiac patients with retinal emboli before coronary catheterization and the proportion with newly developed retinal embolism shortly after coronary catheterization. METHODS: Ninety-seven patients attending Westmead Hospital for coronary catheterization between December 2005 and February 2006 were recruited. Medical history, physical examination, and pre- and postcatheterization photography of 5 retinal fields was performed. The proportion of patients with new retinal emboli was assessed by comparing post- and precatheterization retinal photographs. RESULTS: Before catheterization, retinal emboli were observed in 5 patients (5.2%) and were significantly associated with higher body mass index (P=0.007). The presence of angiographic coronary artery disease was not significantly associated with preexisting retinal emboli. In 97 patients, we found no new emboli within the 16-hour (median: range 4 to 45 hours) postcoronary catheterization period. CONCLUSIONS: Asymptomatic retinal emboli are relatively common in patients being assessed for coronary artery disease. We found no evidence suggesting coronary catheterization contributes to retinal embolism shortly after the procedure.

Protection of the coronary arteries during epicardial radiofrequency ablation with intracoronary chilled saline irrigation: assessment in an in vitro model.

INTRODUCTION: The coronary arteries can be damaged during epicardial radiofrequency ablation (RFA) procedures. We hypothesized that intracoronary irrigation with chilled saline may be a useful technique for minimizing heat-induced damage to the coronary artery endothelium during this procedure. METHODS AND RESULTS: Twenty-nine ablation procedures were performed on 17 freshly excised ovine hearts. Radiofrequency current was delivered through an internally cooled, 4-mm-tip ablation catheter placed directly over the coronary artery (24 applications) and over noncoronary epicardium (5 applications). An Amplatz coronary catheter was used to internally irrigate the coronary artery with either 37 degrees C or 5 degrees C 0.9% saline (12 ablations each group). Fluroptic temperature probes were placed within the artery lumen under the ablation site and 15 mm distal from the ablation site. The peak intracoronary temperature directly under the ablation catheter was significantly lower (P = 0.001) in the chilled than in the nonchilled saline irrigation group (23.6 degrees C, interquartile range [IQR] 15.7-39.8 vs 54.6 degrees C, IQR 48.9-58.6). Blue tetrazolium stained lesion sections showed that the median distance between the ablation lesion and the artery wall was significantly higher (P = 0.004) for the chilled versus the nonchilled saline irrigation group (0.42 mm, IQR 0.25-0.70 vs 0.00 mm, IQR 0.00-0.28). CONCLUSIONS: Intracoronary irrigation with chilled saline may protect the coronary artery endothelium from heat-induced damage during epicardial RFA.
