Upper tract urothelial carcinoma following cystectomy

Metachronous upper tract urothelial cancer (UTUC) is encountered in about 5% of patients after radical cystectomy (RC) with a median time to diagnosis of 24-36 months after RC, and most are asymptomatic and detected by surveillance protocols. In this multivariate...

Emergency department revisits for patients with ureteral stones

The authors aimed to identify clinical predictors for emergency department (ED) revisits in patients diagnosed with ureteral stones. Patients presenting between 2010 and 2013 were included. Those who were admitted at the initial presentation were excluded. CT scans were reviewed...

Refluxing ureteral reimplantation

Obstructed megaureters may be managed with temporising stents, cutaneous ureterostomies, or in older children with ureteral reimplantation (usually if the child is over one year of age). Cutaneous ureterostomies have risks of stomal stenosis, infection and leakage problems over nappies...

Long term outcomes of primary ureterovesicostomy for the primary obstructive megaureter

Primary obstructive megaureter is dilatation of the ureter secondary to narrowing at the vesicoureteric junction (VUJ). Many (80%) require no intervention, however, a select number do for worsening hydroureteronephrosis, decreasing renal function, prolonged drainage time, recurrent urinary tract infections or...

Risk stratified approach to early intervention for renal colic

Existing guidance on this topic is based on older and smaller studies, and there remains variation in practice. This review of database outcomes of 1168 out of 3081 (38%) patients who underwent early intervention after presentation to nine Canadian emergency...

Supranormal function on MAG-3 – what is its significance and how to predict?

Differential renal function (DRF) on MAG-3 scans is typically used in patients with pelvic ureteric junction obstruction (PUJ obstruction). Supranormal DRF is when the kidney with PUJO has higher DRF than the normal contralateral kidney. The authors in this study...

Upper pole access is safe and effective for paediatric percutaneous nephrolithotomy

Upper pole access for percutaneous nephrolithotomy (PCNL) provides a straight access tract to the ureter with easier placement of a guidewire, good exposure of the pelvis and upper ureter, and comfortable manipulations for the treatment of staghorn, large upper caliceal,...

Sacral agenesis and neurogenic bladder: long-term outcomes of bladder and kidney function

These authors looked at single institution outcomes for sacral agenesis (without spina bifida) with reference to renal function and bladder function. All had urodynamics either at diagnosis (56%) or soon after. Of 43 patients (23 female, 20 male), 37 had...

Lower pole vessels in children with PUJO: laparoscopic vascular hitch or dismembered pyeloplasty?

A crossing vessel accompanying pelvi-ureteric junction obstruction (PUJO) occurs in 25-50% of cases. The Hellstrom vascular hitch procedure was first described in 1951 and has regained popularity since 2003 in the era of laparoscopic surgery as it negates the need...
