ABSTRACT
ABSTRACT Microsurgical subinguinal varicocelectomy (MSV) is generally considered the gold standard nowadays in view of the lower risk of complications and recurrence. To achieve complete ligation of veins while preserving testicular artery (TA) during the procedure remains challenging despite the application of high power optical magnification and micro-Doppler ultrasonography. The use of intraoperative indocyanine green angiography (ICGA) with infrared fluorescence operative micro-scope in MSV potentially lowers the incidence of TA injury and shortens the learning curve of novice surgeons. We present our initial experience in the application of the technique in nine patients and explore the potential of the new adjunct.

OBJECTIVE: To review a series of inflammatory myofibroblastic tumours (IMTs) of the urinary bladder in 10 hospitals in Hong Kong. METHODS: A database search in the pathology archives of 10 hospitals in Hong Kong from 1995 to 2013 was performed using the key words 'inflammatory myofibroblastic tumour', 'inflammatory pseudotumour' and 'spindle cell lesion'. Patient characteristics, clinical features, histological features, immunohistochemical staining results and treatment outcomes were reviewed. RESULTS: Nine cases of IMT of the urinary bladder were retrieved. The mean age was 45.4 ± 22.8 years (range 11-78). Eight patients (88.9%) presented with haematuria and 5 patients (55.6%) had anaemia with a mean haemoglobin level of 6.8 ± 1.3 g/dl. Histologically, the majority of patients (77.8%) had a compact spindle cell pattern. Anaplastic lymphoma kinase staining was positive in 75% of cases. During a mean follow-up period of 43.4 months (range 8-94), none of them developed any local recurrence or distant metastasis. CONCLUSIONS: A high index of suspicion of IMT should be maintained for young patients presenting with bleeding bladder tumours and significant anaemia. IMTs of the urinary bladder run a benign disease course, and good prognosis can be achieved after surgical resection.

OBJECTIVE: To retrospectively review our experience of managing patients with emphysematous pyelonephritis (EPN). METHODS: Case notes of patients with EPN were reviewed. The patients' demographic data, clinical presentation, investigation findings, treatment, and outcome were studied. RESULTS: Twelve patients were diagnosed with EPN. Majority (66.7%) of them had diabetes mellitus. All patients had been evaluated by computed tomography (CT). Using the classification proposed by Wan et al, five patients had type 1 EPN, whereas six, two, and four patients had Huang and Tseng CT class 2, 3a, and 3b EPN, respectively. Immediate nephrectomy was performed in six patients, whereas conservative treatment was adopted in the other six. In the nephrectomy group, one patient died of disseminated sepsis after a protracted course. Conservative treatment failed in three patients, who succumbed despite salvage nephrectomy in two of them. Analysis revealed that severe hyperglycemia and radiological CT class (both Wan and Huang systems) were significant predictors of mortality from EPN. CONCLUSION: Severe hyperglycemia and CT class of EPN are significant risk factors for death. CT is the investigation of choice for correct diagnosis of EPN. Additional intervention should be offered to EPN patients with Wan type 1 and Huang and Tseng class 3 CT features.
