Intra-operative pulmonary embolism after intravesical instillation of formalin

Intra-operative pulmonary embolism is a rare and severe complication which is difficult to diagnose. A case is reported in which this condition occurred after intravesical instillation of formalin during radical cystectomy under general anaesthesia. Formalin may be related to formation of intravascular thrombi and result in pulmonary embolism.     

UROLOGICAL TUMOURS: RECENT CHANGES

The principles of urology and all surgical disciplines were, not too long ago, considered to be rigidly and permanently established. In this exciting era of change, the foundations of urology are now set on shifting sands rather than the bedrock of the past. The pertinent issue clinically is making discriminating evaluations of new developments so that, where appropriate. they are able to be incorporated into treatment practices to improve patient care. In this overview, a personal appreciation of the more important practical and conceptual changes relating to prostatic. urothelial and renal carcinoma during the past 5 to 10 years is presented.     

A psychophysiological evaluation of female urethral syndrome: Evidence for a muscular abnormality

This is a preliminary investigation into a recently defined urological disorder occurring in a subgroup of women with urethral syndrome suggestive of pelvic floor muscular (PFM) dysfunction. Symptoms include straining to void, urgency, frequency, hesitation, incontinence and/or retention, and subpubic pain. Finding neither bladder nor urological abnormalities, urologists may consider these women emotionally unstable without organic cause for their symptoms. However, their distress may be a consequence rather than a cause of their voiding problems. Sixteen female urological patients were matched with 16 asymptomatic controls to investigate PFM functioning, psychological status, and symptomatology. Results showed heterogeneity of symptomatology and little elevation of depression or anxiety when comparing patients with controls. Hypotheses of muscular abnormality were confirmed. Patients evidenced poor control over tensing and relaxing PFM, elevations of PFM activity under various conditions, and chronic pain as a prominent symptom. Treatment approaches specifically designed to address PFM dysfunction are discussed.     

The TURP syndrome

This article discusses the presentation, aetiology, treatment and prevention of central nervous system disturbances after transurethral resection of the prostate. Nausea and vomiting, visual symptoms, and altered states of consciousness have been reported as complications due to intravascular absorption of irrigating fluid. Hypotonicity after absorption of the irrigating fluid causes cerebral oedema. Hyperglycinaemia may cause visual disturbances and hyperammonaemia may cause delayed coma.

Lower Extremity Injury While Undergoing Urology Procedures in the Trendelenburg with Lithotomy Position: Three Case Reports

PurposeTo report and discuss the incidence of severe lower extremity injuries associated with robotic procedures in Trendelenburg with lithotomy position.Design and MethodsA case study method was used to describe three cases of patients who underwent robotically assisted urological procedures in Trendelenburg with lithotomy position and developed serious lower extremities injuries resulting in fasciotomies. Furthermore, a literature review was conducted to evaluate risk factors and possible interventions for the prevention of similar injuries.FindingsCase analysis revealed multifactorial causes, including patient comorbidities, long surgical procedures, and blood pressure decreases below the baseline for more than 30 minutes. The severity of lower extremity injury associated with lithotomy position may be underestimated. The etiology of peripheral nerve injury can be attributed to patient comorbidities, positioning, and surgical conditions. Injury prevention should include careful patient and procedural risk assessment, staff education, and communication strategies.ConclusionsExtreme Trendelenburg with lithotomy position for longer periods can lead to serious lower extremities injuries. Preanesthetic screening and multidisciplinary team discussions for additional precautions for high-risk patients are crucial interventions to decrease incidence and severity of lower extremities injuries.     

Ureteral length in live donor kidney transplantation; Does size matter?

The aim of this study was to evaluate the role of ureteral length on urological complications. Data were retrospective collected from the INEX‐trial database, a RCT to compare the intravesical to the extravesical ureteroneocystostomy. Ureteral length was measured in 198 recipients and used to divide recipients into three categories based on interquartile ranges: short (≤8.5 cm), medium (8.6–10.9 cm) and long ureters (≥11 cm). Urological complications were defined as the number of percutaneous nephrostomy placements (PCN). Fifty recipients fell into the short, 98 into the medium and 50 recipients into the long ureter category. Median follow‐up was 26 (range 2–45) months. There was no significant difference in number of PCN placements between the categories. There were 9 (18%) PCN placements in the short ureter category, 21 (20%) in medium ureter category and 10 (21%) in the long ureter category, P = 0.886. Risk factor analysis for gender, arterial multiplicity and type of ureteroneocystostomy showed no differences in PCN placements between the three ureteral length categories. We conclude that ureteral length alone does not seem to influence the number of urological complications.
