How to do an open midline extraperitoneal bilateral retroperitoneal lymph node dissection for non-seminomatous germ cell tumour.

Retroperitoneal lymph node dissection, remains a crucial step in the management of patients with non-seminomatous germ cell tumours who have undergone chemotherapy. It is a technically challenging operation with a number of techniques that have been advocated. We outline the midline, extraperitoneal approach to perform a bilateral template lymph node dissection.

What is the Accuracy of the ACS-NSQIP Surgical Risk Calculator in Emergency Abdominal Surgery? A Meta-Analysis.

BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) surgical risk calculator provides an estimation of 30-d post-operative complications including mortality. This tool has the potential to both aid in decision-making for patients and their families and also in optimizing the clinical management of high-risk patients. However, it's utility in patients requiring emergency abdominal surgery has shown to be inconsistent outside of NSQIP participating institutions. This study undertook a meta-analysis to assess the calculator's accuracy in predicting mortality in these patients. METHODS: A literature search of PubMed, Medline and Cochrane databases was conducted between October 2019 to April 2020. The PubMed, Medline and Cochrane Databases were searched for relevant studies. The search strategy included studies from January 2013 to April 2020. Studies including elective surgery were excluded. A random effects model was used and fitted using restricted maximum likelihood estimation. The O:E ratio was used to validate the calculator's accuracy in predicting mortality. RESULTS: Six studies were included in the meta-analysis, with a total of 1835 patients undergoing emergency intra-abdominal surgery. The summary estimate of the O:E ratio of the ACS-NSQIP surgical risk calculator in predicting 30-d post-operative mortality was 1.06 (95% CI 0.74-1.51). There was significant heterogeneity between studies with a Cochrane Q of 11.96 (P = 0.04) and I2 = 57.5%. CONCLUSIONS: The ACS-NSQIP surgical risk calculator is a reliable predictor of mortality in this external cohort and has potential to be utilised in the multi-disciplinary care of patients undergoing emergency abdominal surgery.

A rare case of an enormous sacral meningocele causing ureteric obstruction.

Sacral Meningoceles, ductal ectasia and pseudomeningoceles are all rare spinal defects that occur due to errors in collagen biosynthesis in the setting of Marfan's Syndrome. Meningoceles, which are extradural collections of cerebrospinal fluid, can form large pelvic collections which can compress local structures. In rare cases, this can lead to extrinsic ureteric obstruction, which can result in acute renal failure and urosepsis. We present a case of a 35-year old female with Marfan's syndrome, with one of the largest sacral meningoceles reported in the literature, causing acute ureteric obstruction, requiring urgent surgical intervention.

Unexpected case of large ureteric calculus being passed following prostatic artery embolisation.

Spontaneous passage of large ureteric calculi over 10mm is uncommon. We present a case of a 69-year-old male with a significant prostatic enlargement (150 cc) and a 13mm ureteric calculus which had not passed for 3 months following a failed attempt at ureteroscopy. His stone passed spontaneously following prostatic artery embolisation (PAE), performed for symptomatic benign prostatic hypertrophy (BPH). We consider the mechanisms by which PAE may impact on the distal ureter which allowed stone passage.

Malakoplakia, a malignant mimic.

Malakoplakia is a chronic inflammatory condition that affects multiple systems, most commonly the urogenital tract. Its clinical presentation is often non-specific, but is typically characterized by recurrent urinary tract infections and haematuria. We report a rare case of intravesical malakoplakia mimicking an aggressive transitional cell carcinoma both in its clinical presentation and in its macroscopic appearance on cystoscopy in an 82-year patient, the oldest reported case in the literature. Malakoplakia has been described in the literature as a benign disease process presenting typically in younger patients. This case demonstrates its ability to cause obstructive uropathy and affect elderly patients. Thus, this case serves as a reminder to consider malakoplakia as a differential in the evaluation of suspected bladder malignancy in patients of all ages.

Segmental testicular infarction, a rare complication of epididymo-orchitis.

Segmental infarction of the testicle secondary to epididymo-orchitis is a rare condition which can be difficult to diagnose and can lead to loss of the testis. We report a case of a 72-year-old man who presented with two weeks of worsening pain of his left testis despite oral antibiotic treatment for epididymo-orchitis. A testicular ultrasound initially revealed a suspected intra-testicular abscess. Despite intravenous antibiotics, his symptoms worsened. A repeat ultrasound demonstrated an increase in size of the lesion and a decision was made to take him to theatre. Intra-operative findings instead revealed a segmental area of testicular infarction requiring debridement.
