Assessing Patient Satisfaction with Kidney Stone Information Advice During Admission for Acute Renal Colic.

Aims This study focuses on the assessment of patient reported outcome measures (PROMs) following an educational intervention by urological service providers. In the modern era, social media and search engines are used as educational tools for both patients and healthcare providers alike. The aim of the study was to assess patient satisfaction with kidney stone information, through the viewing of a novel kidney stone educational video. Methods A prospective quality improvement study was conducted amongst patients admitted to our urology service with kidney stones undergoing emergency ureteroscopy using a patient satisfaction questionnaire. Results Patients reported increased satisfaction with overall information provided about kidney stone prevention after viewing the kidney stone educational video (4.8 vs 4 p=0.01). They also reported increased satisfaction with information provided about diet and lifestyle modification (4.5 vs3 p=0.02) (4.6 vs 3 p=0.02), information and demonstration on stent removal 4.8 vs 3.17 p=0.029), information on stent pain (4.7 vs 2.6 P=0.016) and availability of educational information and resources after viewing the video (4.8 vs 2.83 p=0.017). There were 17 patients in total included for statistical analysis. Conclusion Patient satisfaction with traditional patient education regarding kidney stones can be further strengthened through the use of a concise, informative, and readily accessible patient education video during and after point of care.

Magnetic Stent Removal in a Nurse Led Clinic; a Nine Month Experience.

Ureteric stents are frequently inserted post endourological procedures. However, subsequent endoscopic stent removal requires a second procedure for the patient and the availability of necessary resources. Longer duration of indwelling stents can lead to increased risk of symptoms and complications. The use of magnetic stents removed with a magnetic retrieval device (BlackStar©), offers an alternative which obviates the need for cystoscopy. We assessed the outcomes for this novel method of stent removal in our institution. A retrospective analysis was performed of all patients undergoing magnetic stent insertion and subsequent removal in a nurse-led clinic over a nine-month period. Patients were followed up with a prospective validated Ureteral Stent Symptoms Questionnaire (USSQ)3. A cost analysis was also performed. In total, 59 patients were treated using magnetic stents. The complication rate was low (6.7%). The median duration of indwelling stent was 5.8 days (range 1-11 days). Patients reported haematuria and lower urinary tract symptoms but >90% experienced no functional impairment with minimal days of employment lost (mean 0.75 days). All patients reported satisfaction with nurse-led stent removal and 97% were happy to have stents removed via this method in the future. The total financial savings were estimated at €47,790 over this period. Nurse-led removal of magnetic stents is safe and well tolerated by patients and enables expedient stent removal. It also provides a significant cost benefit and frees up valuable endoscopic resources.

Peri-operative management in urinary diversion surgery: A time for change?

INTRODUCTION: Bowel preparation was established as part of the pre-operative course for patients undergoing ileal conduit formation since the late 1970's. Rationales for its use include reduction in infection and wound complications, technically easier anastomosis and earlier return to bowel function. However, recent reports have challenged this practice. Traditionally antibiotics were also administered for several days prior to surgery with the assumption that bacterial load was reduced. Modification of antibiotic protocols resulted from evidence-based findings. Furthermore, publications emphasizing the benefit of Enhanced Recovery Protocols/Programmes (ERP) have become contemporary. METHODS: An online multiple-choice questionnaire (via Monkey Survey) was administered to all consultant urologists in Ireland. This national cross-sectional study evaluated the use of bowel preparation and antibiotic prophylaxis prior to urinary diversion. In addition, we also assessed consultant urologists' awareness of ERP and their views on the introduction and implementation of such a national program. RESULTS: Of the 41 consultant urologists surveyed, 80.4% (n = 33) responded. 63.6% routinely used bowel preparation. Klean Prep was the most commonly used bowel preparation. 80.9% of urologists admit their patient's one-day pre-operatively for bowel preparation, with 87.8% using antibiotic prophylaxis at anesthesia induction, and 18.1% continuing the antibiotics for 24-48 h post-operatively. Although 74% of consultants are aware of ERP, only 66.6% are in favor of their national implementation. CONCLUSION: The majority of Irish urologists use bowel preparation prior to ileal conduit formation. Substantial recent evidence has emerged showing no difference in infective complications or anastomotic leakage when bowel preparation was not used. National guidelines would be beneficial regarding the use of bowel preparation, antibiotic prophylaxis and ERP for urinary diversion surgery.

Two hit hypothesis: an unusual complication following supra-pubic catheter insertion.

Osteomyelitis is an inflammation of the bone caused by an infection. Though bone is normally resistant to bacterial infection, events including trauma, presence of foreign bodies including prosthesis can act as a nidus for infection. Osteomyelitis is a rare but recognised complication of radiotherapy. Osteomyelitis of the pubis has scarcely been reported as a complication following urological procedures- prostatectomy, sling surgery and catheterisation. We report a rare complication of a gentleman post radiotherapy presenting with delayed osteomyelitis of the pubis following supra-pubic catheterisation.

Incidentalology: A developing urological sub-specialty.

OBJECTIVE: To identify the incidence and features of significant incidental findings discussed at our departmental multidisciplinary team meeting (MDM). The improved quality of radiological imaging has resulted in increased rates of incidental findings. Although some may be trivial, many have clinical significance and early diagnosis and treatment may be beneficial. METHODS: A retrospective analysis was performed of all cases discussed at the MDM between January 2012 and February 2013. Cases were divided into two groups--Group 1 consisted of patients whose initial imaging was performed for a urological presentation which resulted in a synchronous finding; Group 2 consisted of patients who were referred with a synchronous urological finding for discussion following investigation of an initial benign urological condition or a non-urological condition. RESULTS: 696 patients were discussed at 53 MDMs. 109 (15.7%) patients had incidental findings. 61 (56%) of these were in Group 1. 16 (26.2%) were synchronous malignant diagnoses, 25 (41%) were benign and 20 (32.8%) were indeterminate. 48 (44%) patients in Group 2 - 40 (83.3%) were renal in origin and 30 (75%) of these proceeded to surgery. The median tumour size was 3.2 cm (Range: 1.2 cm-10 cm). One patient had radio-frequency ablation. Two were referred for palliative care. Seven patients are under ongoing surveillance--the median size of these lesions is 3.6 cm (Range: 2.1 cm-8.3 cm). CONCLUSION: A substantial workload is generated from the investigation of incidental findings discussed at MDM--these now represent the majority of the caseload for renal cancer surgery.

Perioperative management of chronic anticoagulation therapy in urological patients: a cross-sectional survey of practice.

BACKGROUND: There has been a significant increase in the volume of urological patients on daily anticoagulation therapy requiring invasive elective urological procedures. AIMS: We sought to assess whether urologists are familiar with appropriate perioperative management strategies in this patient cohort. METHODS: Urologists completed a questionnaire on their current management strategy for warfarin during the perioperative period in patients undergoing elective urological surgery. Eleven urological procedures graded as minor, endoscopic and major were assessed in the study. In addition, respondents were also asked whether they administered bridging therapy with heparin when warfarin was discontinued perioperatively. RESULTS: The response rate was 52.5% (210/400). Procedure grade did not influence the duration warfarin was discontinued preoperatively with respondents discontinuing the agent 4.71 ± 1.52 days (range 2-10 days) prior to minor procedures, 4.74 ± 1.43 days (range 2-10 days) prior to endoscopic procedures and 4.88 ± 1.34 days (range 2-10 days) prior to major procedures (p > 0.05). Postoperatively, procedure grade significantly affected the day to recommencement with respondents recommencing warfarin 2.41 ± 2.31 days (range 1-14 days) after minor procedures, 3.07 ± 3.52 days (range 1-28 days) after endoscopic procedures and 4.38 ± 3.53 days (range 1-14 days) after major procedures (p < 0.0001). In total, 60 ± 0.52% of the respondents who discontinued warfarin routinely administered bridging therapy with heparin perioperatively. CONCLUSIONS: Our study demonstrates variations in perioperative management practices for patients on chronic anticoagulation therapy undergoing urological procedures. Urologists should familiarise themselves with standardised guidelines if this patient subgroup are to receive optimal perioperative management.

Porcine extracellular matrix scaffolds in reconstructive urology: An ex vivo comparative study of their biomechanical properties.

Functional reconstruction of the human urinary bladder has been attempted by replacing defective bladder tissue with tissue-engineered xenogenic extracellular matrix (ECM) scaffolds. However, experimental studies that demonstrate the effects of implanted ECMs on important biomechanical properties such as total bladder capacity (TBC) and compliance (C) are lacking. In the current study, the effects of ECM scaffold surface area (SA) on TBC and C was assessed, ex vivo, in an ovine model (n=5). TBC and C were measured at pressures (P) of 5, 10, 15 and 20 mm Hg prior to performing a 3×3 cm (9 cm(2)) partial cystectomy defect. Equal-sized 3×3 cm (9 cm(2)) and larger 6×6 cm (36 cm(2)) urinary bladder matrix (UBM) scaffolds of porcine origin replaced the 3×3 cm cystectomy defect, and TBC and C were re-recorded for comparative analysis. The results showed that TBC decreased by 39.6%±0.005% (122.9 ml±15 ml, p<0.05) and C by 38.9%±0.51%, (ΔP=0-5mmHg, p<0.05) in ovine bladders reconstructed with 3×3 cm UBM scaffolds compared to their native values. It was also found that TBC increased by 25.6±0.64% (64.2 ml ± 8.8 ml, p>0.05) and C by 24.5±0.43% (ΔP=0-5mmHg, p>0.05) in the 6×6 cm UBM scaffold group compared to the 3×3 cm UBM scaffold group; however, these values were not statistically significant. The present work demonstrates that a fourfold increase in ECM scaffold SA relative to its intended defect does not lead to a significant improvement in TBC and C values.

Xenogenic extracellular matrices as potential biomaterials for interposition grafting in urological surgery.

PURPOSE: The field of tissue engineering focuses on developing strategies for reconstructing injured, diseased, and congenitally absent tissues and organs. During the last decade urologists have benefited from remodeling and regenerative properties of bioscaffolds derived from xenogenic extracellular matrices. We comprehensively reviewed the current literature on structural and functional characteristics of xenogenic extracellular matrix grafting since it was first described in urological surgery. We also reviewed the clinical limitations, and assessed the potential for safe and effective urological application of extracellular matrix grafting in place of autogenous tissue. MATERIALS AND METHODS: We performed literature searches for English language publications using the PubMed® and MEDLINE® databases. Keywords included "xenogenic," "extracellular matrix" and "genitourinary tract applications." A total of 112 articles were scrutinized, of which 50 were suitable for review based on clinical relevance and importance of content. RESULTS: Since the mid 1990s xenogenic extracellular matrices have been used to successfully treat a number of pathological conditions that affect the upper and lower genitourinary tract. They are typically prepared from porcine organs such as small intestine and bladder. These organs are harvested and subjected to decellularization and sterilization techniques before surgical implantation. Bioinductive growth factors that are retained during the preparation process induce constructive tissue remodeling as the extracellular matrix is simultaneously degraded and excreted. However, recent documented concerns over durability, decreased mechanical strength and residual porcine DNA after preparation techniques have temporarily hampered the potential of extracellular matrices as a reliable replacement for genitourinary tract structures. CONCLUSIONS: Extracellular matrices are a useful alternative for successfully treating a number of urological conditions that affect the genitourinary tract. However, clinical concerns regarding mechanical limitations and biosafety need to be addressed before their long-term role in reconstructive urological surgery can be clearly established.

Initial experience with transperitoneal laparoscopic nephrectomy in an Irish hospital setting.

INTRODUCTION: Laparoscopic nephrectomy has gained widespread acceptance as a treatment for both benign and malignant conditions and is becoming increasingly popular in Irish hospitals. We report a single surgeon, single centre experience with 20 consecutive laparoscopic nephrectomies comparing them to 20 open cases performed prior to the establishment of a laparoscopic service. METHODOLOGY: A retrospective comparative analysis was carried out over an 18 month period. Transperitoneal approach was used in the laparoscopic group with renal vessels divided using an Endo GIA stapling device. Parameters examined included age, weight, indication, operative time, blood loss, tumour size, length of stay and analgesic requirements. Comparison was made with 20 open nephrectomies. RESULTS: Mean age (p=0.26) and weight (p=0.08) were similar in both groups. Average tumour size was similar (4.98 cm [range 2.8-9] in laparoscopic group versus 6.4 cm [range 3-10], p=0.61). Mean operative blood loss was reduced in the laparoscopic group (65 ml (range 50-200) versus 351 ml (50-1740) (p=or<0.05 L.N. versus O.N.). Laparoscopic patients were discharged earlier; 3.9 days (range 3-6) versus 6.5 (range 5-11) postoperatively (p=or<0.05 L.N. versus O.N.). Analgesia requirements were reduced in terms of both total hours using PCA (25.05 hours [range 1-45] versus 41.6 hours (range 7-226)) (p=or<0.05 L.N. versus O.N.) and total morphine requirements (35.5 mg [range 2-94] versus 72.4 mg [range 18-113] [p=or<0.05 L.N. versus O.N.]). There were no complications in the laparoscopic group, while one patient developed an incisional hernia in the open group. CONCLUSION: Laparoscopic nephrectomy is less invasive and demonstrates improved results in terms of analgesia, blood loss and reduced overall stay.

Should patients with symptomatic BPH have a trial of medical therapy by their general practitioner prior to referral for urological assessment?

The British Association of Urological Surgeons (BAUS) has recently recommended guidelines for the management of Lower Urinary Tract Sypmtoms by GPs outlining the indications for urological referral. We wished to assess the prescription of medical therapy by GPs in the referrals to our LUTS pre-assessment clinic. 115 consecutive patients were reviewed prospectively, over a three month period. Each patient was assessed for International Prostatic Symptom Score (IPSS) and Bother Score, uroflowometry with post void residual and whether medical therapy had been commenced (D-Blocker or 5-D-Reductase inhibitor). The majority of patients (75%) were classified with moderate symptoms. Only 10% of those with moderate symptoms and 5% of those with severe symptoms were commenced on medical therapy by their GP as recommended by the BAUS guidelines. Only 30 patients (26%) had completed an IPSS form with their GP. The majority of patients referred to our service for assessment of LUTS have at least moderate symptom severity and are not prescribed medical therapy by their GP. Further primary care education with greater emphasis on the BAUS LUTS algorithm prior to referral to an urologist should be encouraged.

Ileal pouch-anal anastomosis.

BACKGROUND: Since 1977, restorative proctocolectomy with ileoanal anastomosis (IAA) has evolved into the surgical treatment of choice for most patients with intractable ulcerative colitis. Construction of an ileal pouch reservoir is now standard, usually in the form of J pouch (IPAA). The aim of this report is to review selection criteria for, and functional outcomes, follow-up and management of complications of IPAA after 30 years of widespread clinical application. METHODS AND RESULTS: Literature published in English on the clinical indications, surgical technique, morbidity, complications and outcome following IAA and IPAA was sourced by electronic search, performed independently by two reviewers who selected potentially relevant papers based on title and abstract. Additional articles were identified by cross-referencing from papers retrieved in the initial search. CONCLUSION: The functional results of IPAA are good. Pouchitis, irritable pouch syndrome and cuffitis are specific long-term complications but rarely result in failure. Pouch salvage is possible in selected patients with poor functional outcomes. One-stage operations are increasingly performed.

Testicular vasculitis mimicking a testicular neoplasm.

Vasculitis of the testis generally presents as a manifestation of systemic vasculitis which is well documented. In isolation, it has only been described on few occasions previously, and hitherto it has been in the young. It often mimics a neoplasm of the testis resulting in radical orchidectomy, only for it to be diagnosed when the specimen is examined under the microscope. In our case, an elderly man presented to us with a presumed testicular neoplasm, however, despite strong clinical and radiological suspicion a testicular vasculitis in isolation was revealed. Following our experience, we performed a literature review and examined all of the cases of testicular vasculitis reported so far and present our findings. We report the general clinical presentation, methods of investigation and subsequent management. This is the first time it has been described in the elderly population.

'Bouncy castles' and cervical spine fractures: an under-recognized hazard.

We have recently treated two adult patients with significant spinal injuries after using an inflatable 'bouncy castle'. We highlight the risks associated with these devices in the adult age group and review the current literature. We conclude that these devices should carry a clear warning to adults that their use by above-14 is hazardous.
