Catecholamine-secreting tumours are rare, neuroendocrine tumours that arise from chromaffin cells in the adrenal medulla or sympathetic chain. They are divided into phaeochromocytomas (intra-adrenal) and paragangliomas (extra-adrenal). These lesions emit catechola- mines into the circulation triggering hypertension, headaches, dia- phoresis, palpitations and tremors. Due to the variety of non-specific symptoms, the diagnosis of these lesions can be especially challenging.
Pelvic fracture urethral injuries (PFUI) result from traumatic disruption of the urethra. A significant proportion of cases are complex rendering their management chal- lenging. We described management strategies for eight different complex PFUI scenarios. Methods: Our centre is a tertiary referral centre for complex PFUI cases. We maintain a pro- spective database (1995e2016), which we retrospectively analysed. All patients with PFUI managed at our institute were included.
This case demonstrates the use of 123I-MIBG scintigraphy in the diagnosis of testicular adrenal rest tumours (TART) in an adult with classical congenital adrenal hyperplasia (CAH). TART are common in CAH patients, with MIBG scanning offering a new imaging modality to potentially help verify the diagnosis and prevent invasive investigation.

Boys with high imperforate anus have a recto urethral fistula, which usually occurs at the prostatomembranous junction.
Recent trend is to perform a single stage posterior sagittal posterior anorectoplasty (PSARP) with pull through and closure of fistula. Inadvertent posterior urethral injury during repair may result in traumatic obliteration.
The use of methylene blue dye (MB) to highlight anatomical structures in urology has been well-established. Urethral stricture may extend about a centimeter beyond the abnormal area seen on ure- throgram. Although the current literature suggests a tension-free and end- to- end anastomosis after exci- sion of the strictured urethral segment with spongio brosis and surrounding corpus spongiosum in short bulbar strictures, some centers dealing with urethroplasty prefer anastomosis for short bulbar strictures while others prefer augmentation. With this study, use of MB for delineating stricture line and assessing spongio brosis in the diagnosis of urethral stricture was evaluated.
Pelvic Fracture Urethral Injuries (PFUI) are complex injuries. Traditionally the gap between the disrupted urethral ends has been assessed by retrograde urethrogram (RGU) and voiding cystourethrogram (VCUG).
MRI has been used in assessing the urethral gap (1,2). We present a simple modification of the MRI protocol to achieve better image acquisition which resembles the conventional imaging and is easier to interpret by urologists.
Panurethral strictures represent a complex subgroup of urethral strictures. Lichen sclerosis is the commonest cause for these strictures. We outline the management of panurethral strictures in this review.
In pelvic fracture, the urethral injury is usually bulbo – membranous. Rarely there is bladder neck injury(BNI). Bladder Neck Injuries should be treated primarily. If bladder neck is not treated primarily it may will lead to urinary incontinence and urinoma collection.
A recent study shows that adipose – derived system cells are able to counteract urethral stricture formation in rats. Adipose tissue is a multifunctional organ that contains various cellular types, such as mature adipocytes and the stromal vascular fraction(SVF).
A Minimally – invasive endoscopic approach, using a liquid buccal mucosal graft(LBMG), for management of urethral stricture has recently been published as a poof – of -concept in an animal model (PMID 27177425).
Xanthogranulomatous Pyelonephritis (XGP) is a rare condition characterized by chronic granulomatous inflammation of renal tissue [1,2]. This can be due to obstruction, urinary tract infection and renal calculi [1-5]. The exact pathophysiology and progression of this condition is poorly understood, but altered immune response, changes in lipid metabolism, disturbances in leukocyte function, lymphatic obstruction, venous occlusion/haemorrhage, malnutrition, arterial insufficiency and necrosis of pericalyceal fat.
Complex penile strictures are usually repaired using a two-stage urethroplasty. Buccal mucosal graft (BMG) placed in the rst stage can have a signi cant contraction rate, which may require a subsequent revision surgery. We describe a composite two-stage penile urethroplasty using BMG for patients of complex penile strictures who have some salvageable urethral plate.
Pelvic fracture urethral injuries commonly result from motor vehicle collisions, and the mechanism of injury conventionally thought was a shearing injury at the membranous urethra, which would destroy the striated sphincter.
Urinary tract infections (UTIs) commonly occur in children. An estimated 8% of girls and 2% of boys will have at least one episode by seven years of age. Of these children, 12-30% will experience recurrence within one year.
A 63 year old female presented with two days of right-flank pain,fever and vomiting. Her past medical history was significant for total abdominal hysterectomy (TAH), hypertension, kyphoscoliosis, rheumatoid arthristis on methotrexate and recurrent urinary tract infections , more than monthly from early adulthood.
A 66-year-old man was referred by his general practitioner for management of lower urinary tract symptoms. The patient reported minor voiding symptoms but denied incontinence. Physical examination revealed two urethral opening on the dorsal aspect of the glans . The patient reports passing urine through both openings but had never reported this to his doctor.
Renal cysts are common and most often are discovered incidentally, but may require intervention if associated with pain, hypertension, or hematuria. Minimally invasive treatment options are preferred with numerous modalities available, including renal cyst ablation.

To describe the natural history and quality of life (QoL) in patients with cystine urolithiasis. A cohort study was carried out involving participants recruited from a single surgeon’s case mix. Patients with cystinuria and related urolithiasis were invited to complete a questionnaire involving demographic information, use of medical treatment, surgical interventions and the 36-item short-form 36-item short-form health survey (SF-36).

The aim of this study was to assess the outcomes of early vascular release in robot-assisted laparoscopic partial nephrectomy (RAPN) to reduce warm ischaemia time (WIT) and minimise renal dysfunction. RAPN is increasingly utilised in the management of small renal masses.

Clear cell adenocarcinoma arising out of endometriosis of the urinary bladder is a rare entity. The published literature has a dearth of information about this entity and its histogenesis. In the present case review we present a 59-year-old patient who was treated with robotic anterior pelvic exenteration and ileal conduit.
GISTS (Gastrointestinal stromal tumours) are malignant form of sarcoma of the digestive tract. Various unusual presentations and morphological variants of GIST have been described, including extramural components of GIST. The literature has no reference regarding an extramural hemangiomatous component of a GIST.
A 57-year-old male presented with right upperabdominal lump since 3 months. He was diagnosed to havea hepatic artery aneurysm. He was investigated thoroughly but no cause was found. He was subjected to endovascularembolisation of the aneurysm using endovascular coils.Subsequently the aneurysm was completely occluded.Hepatic artery aneurysms are very rare among all visceralaneurysms.
