Non-visible haematuria: would discontinuing urgent investigation have a visible impact?

National guidance in the UK continues to recommend urgent referral of selected patients with non-visible haematuria for urological assessment. The positive predictive value of non-visible haematuria for urological cancer is low, so it is uncertain whether this is an effective and equitable use of healthcare resources. This article considers rationales for and against continuing this practice, and outlines alternative investigative strategies for patients presenting with non-visible haematuria based on current knowledge and modern technology.

Risks and Benefits of Adjuvant Radiotherapy After Inguinal Lymphadenectomy in Node-positive Penile Cancer: A Systematic Review by the European Association of Urology Penile Cancer Guidelines Panel.

CONTEXT: Management of men with penile squamous cell carcinoma (PSCC) who have high-risk features following radical inguinal lymphadenectomy (ILND) remains controversial. European Association of Urology guidelines state that adjuvant inguinal radiotherapy (AIRT) is "not generally recommended". Despite this, many centres continue to offer AIRT to a subset of men. OBJECTIVE: To undertake a systematic review of the evidence on AIRT in node-positive men with PSCC. EVIDENCE ACQUISITION: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with no language or date restriction. Inclusion criteria were men with PSCC, pathologically staged inguinal node positive after ILND. The intervention included ILND with AIRT compared with ILND alone. Primary outcomes were relapse-free survival and toxicity. Risk of bias assessment was undertaken. EVIDENCE SYNTHESIS: A total of 913 abstracts were identified and screened independently by two reviewers. Seven studies were eligible for inclusion: six full-text manuscripts and one conference abstract. All were retrospective series and at a high risk of bias. The selected studies included 1605 men. Indications for AIRT varied but were typically involvement of two or more inguinal nodes or extranodal extension. Regional recurrence rate following AIRT was reported at 10-91.7%. Only one study reported on toxicity. Two studies compared recurrence and survival between men who received and who did not receive AIRT, with no significant difference (p>0.05). CONCLUSIONS: The evidence indicates that men treated with AIRT do not gain benefit with respect to relapse or survival. Uncertainty remains due to the retrospective nature and high risks of bias across the evidence. Given the lack of evidence supporting AIRT, it cannot be recommended for routine practice. PATIENT SUMMARY: Men with penile cancer who have involvement of the inguinal lymph nodes are at a high risk of cancer recurrence and death. We reviewed the literature to see if radiation treatment after removal of the nodes provided benefit. We did not find any good-quality evidence supporting this treatment, and hence it cannot be recommended.

A rare urological presentation of appendicitis.

A 17-year-old boy with no medical comorbidities, but a significant family history of malignancy, presented to Accident and Emergency following 3 days of increasing rectal pain, symptoms of bladder outflow obstruction (poor flow, intermittent stream and hesitancy) and dysuria. Notably he had no abdominal pain. Digital rectal examination revealed a tender, enlarged prostate. Inflammatory markers were significantly raised (white cell count 17.7, C reactive protein 191). He was diagnosed clinically as prostatitis and commenced on intravenous antibiotics. Despite this his pain and inflammatory markers deteriorated, necessitating a CT of his abdomen and pelvis. This demonstrated multiloculated large thick-walled abscesses in the pelvis closely related to the rectum, prostate and seminal vesicles with some bowel wall thickening. Laparoscopy demonstrated a large colonic mass adherent to surrounding structures. The procedure was converted to laparotomy to enable resection of the mass via a limited right haemicolectomy. He recovered well and was discharged. Histopathological analysis of the specimen revealed appendicitis.

Effect of Chinese Herbal Medicine on Male Infertility.

Male infertility normally refers a male's inability to cause pregnancy in a fertile female partner after 1 year of unprotected intercourse. Male infertility in recent years has been attracting increasing interest from public due to the evidence in decline in semen quality. There are many factors contributing to the male infertility including abnormal spermatogenesis; reproductive tract anomalies or obstruction; inadequate sexual and ejaculatory functions; and impaired sperm motility, imbalance in hormone levels, and immune system dysfunction. Although conventional treatments such as medication, surgical operation, and advanced techniques have helped many male with infertility cause pregnancy in their female partners, effectiveness is not satisfactory and associated with adverse effects. Chinese herbal medicine (CHM) has been used to improve male infertility in China for a very long time and has now been increasingly popular in Western countries for treating infertility. In this chapter we summarized recent development in basic research and clinical studies of CHM in treating male infertility. It has showed that CHM improved sperm motility and quality, increased sperm count and rebalanced inadequate hormone levels, and adjusted immune functions leading to the increased number of fertility. Further, CHM in combination with conventional therapies improved efficacy of conventional treatments. More studies are needed to indentify the new drugs from CHM and ensure safety, efficacy, and consistency of CHM.

Sentinel lymph node biopsy in renal malignancy: The past, present and future.

Sentinel lymph node biopsy (SLNB) is now an established technique in penile and pelvic cancers, resulting in a lower mortality and morbidity when compared with the traditional lymph node dissection. In renal cancer however, despite some early successes for the SLNB technique, paucity of data remains a problem, thus lymph node dissection and extended lymph node dissection remain the management of choice in clinically node positive patients, with surveillance of lymph nodes in those who are clinically node negative. SLNB is a rapidly evolving technique and the introduction of new techniques such as near infra-red fluorescence optical imaging agents and positron emission tomography/computed tomography scans, may improve sensitivity. Evidence in support of this has already been recorded in bladder and prostate cancer. Although the lack of large multi-centre studies and issues around false negativity currently prevent its widespread use, with evolving techniques improving accuracy and the support of large-scale studies, SLNB does have the potential to become an integral part of staging in renal malignancy.

Early access ligation resolves presumed ischaemic monomelic neuropathy in a patient with recurrence of central venous occlusion.

PURPOSE: Ischaemic monomelic neuropathy (IMN) is a rare but serious complication of haemodialysis access procedures, with a highly variable clinical presentation. We present a case of presumed IMN managed with ligation of the prosthetic brachial-axillary access, leading to recovery of neurological function. METHODS: A 75-year-old male who underwent placement of a left prosthetic brachial-axillary access developed a swollen left upper limb following surgery and underwent interventional management for central venous occlusion. RESULTS: Eleven weeks following placement of the access, he presented with gross swelling and loss of function in the left arm. Ultrasonography excluded nerve compression. The brachial-axillary access was urgently ligated, leading to recovery of function in the arm. Electromyography (EMG) studies confirmed an ischaemic cause. CONCLUSIONS: The pathophysiology of IMN is poorly understood. This case is atypical in that the patient suffered from central venous stenosis prior to the development of IMN. This raises the possibility that the gross swelling secondary to recurrent central venous occlusion may have led to an ischaemic neuropathy by altering nerve perfusion. Early management led to a functional recovery of the affected limb, suggesting that an urgent approach in patients with suspected IMN might be associated with the best outcomes.
