Introduction: We wanted to collect contemporary data
on the pathway from referral to discharge in a consecutive
cohort of patients undergoing emergency scrotal exploration. Secondly, we wanted to assess for pre-operative
investigations that may correlate with the finding of torsion at operation.
Materials & Methods: Patients with suspected torsion
were prospectively identified in different hospitals within a
single region in the UK. Patient data was collected from
June 2017 to November 2017.
Results: 116 consecutive patients were included in this
study, median age 13 (range 0.25-68 yrs). 97% of patients
presented with pain, 54% swelling, 34% skin changes, 2.5%
lower urinary tract symptoms and 2% with fever. Median
transfer time for Urological assessment was 45 (range
0-300 min). Median time to theatre was 90 (range 15-720
min). 42% of patients had a urinalysis prior to theatre. 22%
patients had routine bloods. Eight patients had pre-operative ultrasound (US), with 100% correlation to surgical
findings. Operative findings were: torsion 20%, torted
hydatid 30%, epididymo-orchitis 18%, negative findings
30% and other pathology 2%. 41% of patients had a three
point orchidopexy. Four patients underwent orchidectomy. 2.5% had immediate complications. 72% of patients
responded to six week follow up which identified 5%
wound infection, 6% pain and 7% palpable suture. No reexplorations were performed.
Conclusions: This multicentre study has confirmed a
relatively low rate of testicular torsion and short term
complications. Interestingly the study highlights the need
for a larger scale study to re-evaluate the role of preoperative US in patients undergoing scrotal exploration.

Introduction: Constantly increasing patient numbers
create severe pressure on outpatient clinics. New patient
care pathways are needed that can reduce those pressures and improve patient overall care.We set up a weekly
virtual stone clinic whose aim was to ensure that all stone
patients were reviewed by the stone team and triaged to
the appropriate stream. All stone referrals were captured
by the Stone Coordinator and reviewed in the VSC by the
Stone Consultant(s), SpR, Stone Nurse and Research
Nurse.
Aim and Methods: We aimed to assess the effectiveness
of our virtual stone clinic in saving outpatient appointments, diverting consultant clinic appointments to nurse
led consultations (in person or via telephone) and expediting patient care pathways to meet treatment target

69
pressures. Data were collected prospectively for 5 months
from 12/12/16 to 17/5/17.
Results: The VSC reviewed 300 clinic appointment
requests. Of those 65 appointments were avoided completely, 45 were changed to telephone appointments and
127 to specialist nurse appointments. In addition 178
patients were referred for opinion. In 24 the management
decision was altered avoiding last minute cancellations
after re-discussion with the patients. Clinic appointments
were expedited in 17 cases for clinical reasons and 6
patients were admitted for urgent intervention.
Conclusion: We found that utilizing a 90 minute VSC
every week has significantly reduced outpatient clinic
pressures, expedited patient care in appropriate cases and
prevented last minute changes to procedures or cancellations. Overall it improved patient management while saving significant resources in terms of time and money.
P7-10 Device to remotely monitor catheter
output: results of a pilot trial

Introduction & Objectives: Approximately half a million people in the UK have a long-term urinary catheter.
Early recognition and intervention in catheter-associated
UTI can prevent hospitalisation and decrease both morbidity and mortality.This study examines a device, invented
by the author, that continuously monitors the output of a
foley catheter and communicates this information wirelessly to a remote monitoring system.
Materials & Methods: The small device fits easily
between the outflow of a foley catheter and the inflow of
the catheter bag. It continuously monitors urine flow, temperature and concentration. It can detect the presence of
blood in the urine and gauge the degree of haematuria. It
additionally connects to the catheter balloon, measuring
intra-abdominal pressure. The data are continuously
recorded and are transmitted wirelessly via a patient's
smartphone or home-router to a cloud based monitoring
system. We ran various laboratory simulations to judge
the efficacy of the device during its development.
Results: The device is able to determine the temperature,
concentration and degree of haematuria with an accuracy
similar to current 'gold standard' tests. The changes in
pressure in the catheter balloon can identify early blockage of the catheter, by demonstrating rising bladder pressure. The device does not appear to block with simulated
blood clots.
Conclusions: The device will require further clinical trials to determine its safety, however it has significant
potential to be able to identify catheterised patients at
risk of UTI, haematuria and catheter blockage.
