647 Management of Malignant Upper Urinary Tract Obstruction

Background

Malignant Upper Urinary Tract Obstruction (MUUTO) is a common emergency presentation. These are often complex patients and require multiple specialty input to make time-critical decisions. There are currently no national guidelines for the management of MUUTO, a review was conducted to assess the management and outcomes of MUUTO.

Aim

To agreed and review a pathway for patients with MUUTO in order to streamline patient care and to review the management.

Method

The pathway was devised by several consultants at Oxford University Hospital. Through retrospective data collection, the outcomes over six months were reviewed.

Results

Over the six-month period 49 interventions were performed for MUUTO; 44 Percutaneous Nephrostomy (PCN) and five cystoscopies with retrograde ureteric stents (RUS). Patients were admitted to urology in 45% of cases and oncology in 39%. The obstruction was located above the pelvis in 16 (33%) of the cases and within the pelvis in 25 (51%). The most common cancers causing obstruction were bladder cancer (41%), prostate (16%), and colorectal (14%). MDT advice was sought in 63% of cases. The mean time from diagnosis to the intervention was four days. Of the five retrograde inserted ureteric stents, four were unsuccessful and the patients proceeded to PCN. At the conclusion of data collection, 26 (53%) patients had died.

Discussion

The most striking findings were the high failure rate of RUS and the overall poor prognosis of MUUTO. As such this review suggests that more patients should proceed directly to PCN for decompression.

327 Relative Benefits of Extracorporeal Shockwave Lithotripsy (ESWL) Compared to Observation in Acute Renal Colic

Aim

NICE guidance recommends patients with renal colic be offered surgical treatment, including extracorporeal shockwave lithotripsy (ESWL), within 48 hours if pain is uncontrolled or stones unlikely to pass. We compared outcomes for ureteric stone passage after ESWL with those of observation to ascertain the relative benefits of ESWL.

Method

We collected data on stone location, size, and number of ESWL treatments required prospectively over 18 months. Stone passage was confirmed radiologically. Data were compared with MIMIC, a multi-centre collaborative study examining spontaneous stone passage after observation alone.

Results

166 patients had ESWL for ureteric stones. Median size was 6.5mm (IQR 5.0-8.0mm). 57.2% (N = 95) were proximal stones. Smaller stones required fewer treatments (P = 0.003). Patients with a ureteric stone <5mm required median 1.0 ESWL treatments (IQR 1.0-2.0). Ureteric stones 5-7mm had median 1.0 treatments (IQR 1.0-2.0) and stones >7mm median 2.0 treatments (IQR 1.0-2.0). Compared to MIMIC, patients with ESWL for stones <5mm were 11% more likely to achieve stone clearance (100.0% vs 89.0%, P = 0.001). ESWL for 5-7mm stones had 28.1% greater clearance compared to observation (77.1% vs. 49.0%, P < 0.001) and ESWL for stones >7mm 21% greater likelihood of clearance (50.0% vs. 29.0%, P < 0.001). Proximal ureteric stones were 16.4% more likely to pass with ESWL than observation (68.4% vs 52%, P = 0.02). Distal stones showed similar passage with ESWL (77.5%) and observation (83.0%), P = 0.43.

Conclusions

Proximal ureteric stones and those >5mm stones benefit most from ESWL. Results aid identification of patients whose stones are less likely to pass and warrant urgent review to consider ESWL.

Kick the habit: a social marketing campaign by Aboriginal communities in NSW

Tackling smoking is an integral component of efforts to improve health outcomes in Aboriginal communities. Social marketing is an effective strategy for promoting healthy attitudes and influencing behaviours; however, there is little evidence for its success in reducing smoking rates in Aboriginal communities. This paper outlines the development, implementation and evaluation of Kick the Habit Phase 2, an innovative tobacco control social marketing campaign in Aboriginal communities in New South Wales (NSW). The Aboriginal Health & Medical Research Council worked with three Aboriginal communities and a creative agency to develop locally tailored, culturally relevant social marketing campaigns. Each community determined the target audience and main messages, and identified appropriate local champions and marketing tools. Mixed methods were used to evaluate the campaign, including surveys and interviews with community members and Aboriginal Community Controlled Health Service staff. Community survey participants demonstrated high recall of smoking cessation messages, particularly for messages and images specific to the Kick the Habit campaign. Staff participating in interviews reported an increased level of interest from community members in smoking cessation programs, as well as increased confidence and skills in developing further social marketing campaigns. Aboriginal community-driven social marketing campaigns in tobacco control can build capacity, are culturally relevant and lead to high rates of recall in Aboriginal communities.

Isolated avulsion fracture of the coronoid process requiring open reduction in a paediatric patient: a case report

Coronoid process fractures are reported to occur from avulsion by the brachialis muscle or to be associated with elbow dislocations. We report a rare case of coronoid process fracture due to avulsion by the anterior bundle of the medial collateral ligament rendering the elbow unstable. In children, small fracture fragments of the coronoid process (types 1 & 2) are in reality often much larger but the actual size is not appreciated radiographically, as the coronoid process contains considerable amounts of cartilage. If the fragment is seen to be significantly displaced it may have resulted from avulsion by important structures such as the medial collateral ligament and open reduction is required to stabilise the elbow.
