A rare complication of ureteral stenting: Case report of a uretero-arterial fistula and revision of the literature

Introduction: Uretero-arterial fistulas are a rare condition. The most frequent clinical sign is hematuria. Since these bleedings occur intermittently, the diagnosis is very difficult. If not discovered, uretero-arterial fistulas involve a very high rate of mortality or even results in loss of kidney function. Case report: The clinical case we describe is an unusual one. After a radical hysterectomy and a subsequent radiotherapy, a hydronephrosis caused by ureteral fibrosis occurred on both sides. Therefore, the patient received bilateral ureteral stents. During a change of the ureteral stents 18 months later, a massive bleeding appeared in the right ureter. Initially, a clear evidence of a fistula was not possible - neither through CT scan nor through selective angiography. There were some indicators of a uretero-arterial fistula, so an endoluminal vessel stent was placed. Subsequently the fistula probably led to an erosion of the vessel stent. Discussion: A fistula between the ureter and the iliac artery (UAF) is a rare complication. The increase in known cases during the last years is linked to the possibility of ureteral stenting since 1978. Until now only 140 cases have been described in literature. The mortality rate through UAF has decreased from 69% in 1980 to 7-23% today. Its development can be traced through the pulsation of the artery and the pressure on the ureter. The most important clinical symptom is bleeding. Diagnosis is generally difficult and represents the real problem. The sensitivity of the standard angiography examination is 23- 41%; it can be improved to 63% using the “provocative” method, which means mobilizing the ureteral stent during examination. The therapy in course of the angiography consists of a simultaneous endovascular stent and/or a co-embolisation. Conclusion: Arterial or uretero-arterial fistulas (UAF) are a rare condition; the diagnosis is very difficult and most of the time the treatment requires a multidisciplinary team

Tubular ectasia of the rete testis (TERT). Differential diagnosis of cystic testicular disorders

The ultrasound scan plays an essential role in the urological-andrological diagnosis. High-resolution transducers (8-15 MHz) make it possible to prove increasingly small changes. The assessment of cystic masses in the testis can also be difficult for experienced doctors. However, a precise diagnosis is crucial for the patient to avoid further invasive diagnostics and therapy. The differential diagnosis of benign intra-testicular cystic lesions include the tubular ectasia of the rete testis (TERT), the cystic dysplasia, epidermoid cysts, dermoid cysts, simple testicular cysts and cysts of the tunica albuginea. Malign testicular tumours with cystic changes are particularly the mature teratoma, carcinomas of the epididymis and metastasis. The following overview shows different sonographic images and interpretations with a particular focus on TERT

Attitudes towards career choice and general practice: a cross-sectional survey of medical students and residents in Tyrol, Austria

Abstract Background The global primary healthcare workforce is declining, leading to a shortage of general practitioners. Although various educational models aim to increase interest in general practice, effective interventions are limited. The reasons for this low appeal among medical graduates remain unclear. Methods This cross-sectional study surveyed medical students’ and residents’ attitudes towards general practice in Tyrol, Austria. The online questionnaire addressed professional values, general practice-related issues, personal professional intentions, and demographics. Data analysis employed chi-square tests and multivariate logistic regression to explore predictors of interest in general practice. Results The study included 528 students and 103 residents. Key values identified were stable positions, assured income, and work-family reconciliation. General practice was recognised for long-term patient relationships and patient contact, with students attributing more positive work-environmental characteristics and higher reputation to it than residents. Few participants (students: 3.2%, residents: 11.7%) had opted for general practice; about half were considering it as career option. Reasons not to choose general practice were preferences for other specialties, intrinsic characteristics of general practice, workload, insufficient time for the patients, financial pressures, low reputation, and perceived mediocre training quality. Predictors of interest in general practice included perception of independent decision-making, importance of work-family balance (students), better practical experiences in general practice during medical school (students and residents), younger age, and perceiving general practice as offering a promising future (residents). Both groups felt underprepared by medical school and/or general practice training for general practice roles. The attractiveness of specialist medicine over general practice was related to clearer content boundaries, better career opportunities, and higher incomes. Conclusions According to these results, measures to improve attractiveness of general practice should focus on (i) high-quality undergraduate education including practical experiences, and (ii) on ensuring professional autonomy, work-family reconciliation, and job stability. Efforts to encourage more graduates to pursue this essential healthcare sector are crucial for strengthening primary healthcare and public health services. Trial registration The study has not been registered as it did not include a direct medical intervention on human participants
