Epididymo-orchitis refers to the inflammation of the epididymis and/or testicle. It typically presents with sudden pain, swelling, and inflammation in the affected area. This condition can also occur chronically, which means that the pain and inflammation last for more than six months.

The causes of epididymo-orchitis vary depending on the age of the patient. In men under 35 years old, the infection is usually sexually transmitted and caused by Chlamydia trachomatis or Neisseria gonorrhoeae. In men over 35 years old, the infection is usually non-sexually transmitted and occurs as a result of enteric organisms that cause urinary tract infections, with Escherichia coli being the most common. However, there can be some overlap between these groups, so it is important to obtain a thorough sexual history in all age groups.

Mumps should also be considered as a potential cause of epididymo-orchitis in the 15 to 30 age group, as mumps orchitis occurs in around 40% of post-pubertal boys with mumps.

While most cases of epididymo-orchitis are infective, non-infectious causes can also occur. These include genito-urinary surgery, vasectomy, urinary catheterization, Behcet’s disease, sarcoidosis, and drug-induced cases such as those caused by amiodarone.

Patients with epididymo-orchitis typically present with unilateral scrotal pain and swelling that develops relatively quickly. The affected testis will be tender to touch, and there is usually a palpable swelling of the epididymis that starts at the lower pole of the testis and spreads towards the upper pole. The testis itself may also be involved, and there may be redness and/or swelling of the scrotum on the affected side. Patients may experience fever and urethral discharge as well.

The most important differential diagnosis to consider is testicular torsion, which requires immediate medical attention within 6 hours of onset to save the testicle. Testicular torsion is more likely in men under the age of 20, especially if the pain is very severe and sudden. It typically presents around four hours after onset. In this case, the patient’s age, longer history of symptoms, and the presence of fever are more indicative of epididymo-orchitis.

Testicular torsion is a condition where the spermatic cord twists, leading to a lack of blood flow to the testis. It is a surgical emergency and prompt action is necessary to save the testis. It is most commonly seen in individuals aged 15-30 years.

Varicocele refers to the presence of varicose veins in the pampiniform plexus of the cord and scrotum. It is more frequently observed in the left testis and may be associated with infertility. This is believed to be due to the increased temperature caused by the varicose veins. Symptoms include a dull ache in the testis, which is often worse after exercise or at the end of the day. Standing examination can reveal the presence of Varicocele. Treatment is usually conservative, with surgery reserved for severe cases.

Hydrocoele can occur at any age and is characterized by the accumulation of fluid in the tunica vaginalis. It presents as scrotal swelling, which can be palpated above. The surface of the hydrocoele is smooth and it can be transilluminated. The testis is contained within the swelling and cannot be felt separately. Primary or secondary causes can lead to hydrocoele, and in adults, an ultrasound is performed to rule out underlying pathology such as tumors. Conservative management is often sufficient unless the hydrocoele is large.

Testicular cancer is the most common cancer in men aged 20-34 years. Awareness campaigns have emphasized the importance of self-examination for early detection. Risk factors include undescended testes, which increase the risk by 10-fold if bilateral. A previous history of testicular cancer carries a 4% risk of developing a second cancer. The usual presentation is a painless lump in the testis, which can also manifest as a secondary hydrocoele. Seminomas account for 60% of cases and are slow-growing, usually confined to the testis upon diagnosis. Stage 1 seminomas have a 98% 5-year survival rate. Teratomas, which can grow faster, make up 40% of cases and can occur within seminomas. Mixed type tumors are treated as teratomas due to their more aggressive nature. Surgical treatment, with or without chemotherapy and radiotherapy, is the primary approach.

Epididymo-orchitis is inflammation of the testis and epididymis caused by infection.

The term renal colic is commonly used to describe a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. However, a more accurate term is ureteric colic, as the pain usually arises from a blockage in the ureter itself.

Renal or ureteric colic typically presents with a sudden onset of severe abdominal pain on one side, starting in the lower back or flank and radiating to the genital area in women or to the groin or testicle in men.

The pain usually:
– Lasts for minutes to hours and comes in spasms, with periods of no pain or a dull ache
– Is often accompanied by nausea, vomiting, and blood in the urine
– Is often described as the most intense pain a person has ever experienced (many women describe it as worse than childbirth).

People with renal or ureteric colic:
– Are restless and unable to find relief by lying still (which helps distinguish it from peritonitis)
– May have a history of previous episodes
– May have a fever and sweating if there is a urinary tract infection present
– May complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and bladder (due to irritation of the bladder muscle).

If possible, a urine dipstick test should be done to support the diagnosis and check for signs of a urinary tract infection.

Checking for blood in the urine can also support the diagnosis of renal or ureteric colic. However, the absence of blood does not rule out the diagnosis and other causes of pain should be considered.

Checking for nitrite and leukocyte esterase in the urine can indicate an infection.

Pain management:
– Non-steroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for adults, children, and young people with suspected renal colic.
– Intravenous paracetamol can be given to adults, children, and young people if NSAIDs are not suitable or not providing enough pain relief.
– Opioids may be considered if both NSAIDs and intravenous paracetamol are not suitable or not providing enough pain relief.
– Antispasmodics should not be given to adults, children, and young people with suspected renal colic.

This patient is displaying symptoms and signs that are consistent with a diagnosis of acute pyelonephritis. Additionally, they are showing signs of sepsis, which indicates a more serious illness or condition. Therefore, it would be advisable to admit the patient for inpatient treatment.

According to the recommendations from the National Institute for Health and Care Excellence (NICE), patients with pyelonephritis should be admitted if it is severe or if they exhibit any signs or symptoms that suggest a more serious condition, such as sepsis. Signs of sepsis include significant tachycardia, hypotension, or breathlessness, as well as marked signs of illness like impaired level of consciousness, profuse sweating, rigors, pallor, or significantly reduced mobility. A temperature greater than 38°C or less than 36°C is also indicative of sepsis.

NICE also advises considering referral or seeking specialist advice for individuals with acute pyelonephritis if they are significantly dehydrated or unable to take oral fluids and medicines, if they are pregnant, if they have a higher risk of developing complications due to known or suspected abnormalities of the genitourinary tract or underlying diseases like diabetes mellitus or immunosuppression, or if they have recurrent episodes of urinary tract infections (UTIs).

For non-pregnant women and men, the recommended choice of antibacterial therapy is as follows: oral first-line options include cefalexin, ciprofloxacin, or co-amoxiclav (taking into account local microbial resistance data), and trimethoprim if sensitivity is known. Intravenous first-line options are amikacin, ceftriaxone, cefuroxime, ciprofloxacin, or gentamicin if the patient is severely unwell or unable to take oral treatment. Co-amoxiclav may be used if given in combination or if sensitivity is known. Antibacterials may be combined if there are concerns about susceptibility or sepsis. For intravenous second-line options, it is recommended to consult a local microbiologist.

For pregnant women, the recommended choice of antibacterial therapy is cefalexin for oral first-line treatment. If the patient is severely unwell or unable to take oral treatment, cefuroxime is the recommended intravenous first-line option. If there are concerns about susceptibility or sepsis, it is advised to consult a local microbiologist for intravenous second-line

Conservative management of ureteric stones may involve the use of medical expulsive therapy (MET), which can be achieved through the administration of either an alpha-blocker or a calcium-channel blocker. This treatment aims to facilitate the natural passage of the stone during the observation period.

Research has shown that in adults, both alpha-blockers and calcium channel blockers have been effective in improving the passage of distal ureteric stones that are less than 10 mm in size, when compared to no treatment. Additionally, alpha-blockers have shown to be more effective than placebo in promoting stone passage. Alpha-blockers have also demonstrated more benefits than calcium channel blockers in terms of stone passage, as well as some advantages in terms of hospital stay and pain management. However, there was no significant difference in the time it took for the stone to pass or the overall quality of life.

Currently, the National Institute for Health and Care Excellence (NICE) recommends alpha-blockers as the preferred choice for medical expulsive therapy. For more detailed information, you can refer to the NICE guidelines on the assessment and management of renal and ureteric stones.

Urinary tract stones form when the concentration of salt and minerals in the urine becomes too high. These stones can be classified into five types based on their mineral composition and how they develop.

The most common type of stone is the calcium stone, which can be further divided into calcium oxalate and calcium phosphate stones. These account for 60-80% of all urinary tract stones.

Another type is the struvite or magnesium ammonium phosphate stone, making up about 10-15% of cases. Uric acid stones, also known as urate stones, occur in 3-10% of cases.

Cystine stones are less common, accounting for less than 2% of urinary tract stones. Finally, there are drug-induced stones, which are caused by certain medications such as triamterene, protease inhibitors like indinavir sulphate, and sulfa drugs. These account for approximately 1% of cases.

By understanding the different types of urinary tract stones, healthcare professionals can better diagnose and treat patients with this condition.

For the treatment of men with lower urinary tract infection (UTI), it is recommended to offer an immediate prescription of antibiotics. However, certain factors should be taken into account. This includes considering previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria.

Before starting antibiotics, it is important to obtain a midstream urine sample from men and send it for culture and susceptibility testing. This will help determine the most appropriate choice of antibiotic.

Once the microbiological results are available, it is necessary to review the initial choice of antibiotic. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

The first-choice antibiotics for men with lower UTI are trimethoprim 200 mg taken orally twice daily for 7 days, or nitrofurantoin 100 mg modified-release taken orally twice daily for 7 days if the estimated glomerular filtration rate (eGFR) is above 45 ml/minute.

If there is no improvement in lower UTI symptoms after at least 48 hours on the first-choice antibiotics, or if the first-choice is not suitable, it is important to consider alternative diagnoses and follow the recommendations in the NICE guidelines on pyelonephritis (acute): antimicrobial prescribing or prostatitis (acute): antimicrobial prescribing. The choice of antibiotic should be based on recent culture and susceptibility results.

This is a classical history for a simple urinary tract infection. The other possible causes mentioned can also result in frank haematuria, but they would be less likely based on the given history.

Bladder cancer typically presents with additional symptoms such as an abdominal mass, weight loss, and fatigue. Nephritis is more likely to cause renal angle tenderness and some systemic upset. It is often preceded by another infection.

Tuberculosis may also have more systemic involvement, although it can present on its own. Renal stones commonly cause severe pain from the loin to the groin and renal angle tenderness.

Bladder cancer is the most likely diagnosis in this case, as patients with painless haematuria should undergo cystoscopy to rule out bladder cancer. This procedure is typically done in an outpatient setting as part of a haematuria clinic, using a flexible cystoscope and local anaesthetic.

Prostate cancer is less likely in this case, as the patient’s prostate examination was relatively normal and he only had mild symptoms of bladder outlet obstruction.

Bladder cancer is the seventh most common cancer in the UK, with men being three times more likely to develop it than women. The main risk factors for bladder cancer are increasing age and smoking. Smoking is responsible for about 50% of bladder cancers, as it is believed to be linked to the excretion of aromatic amines and polycyclic aromatic hydrocarbons through the kidneys. Smokers have a 2-6 times higher risk of developing bladder cancer compared to non-smokers.

Painless macroscopic haematuria is the most common symptom in 80-90% of bladder cancer patients. There are usually no abnormalities found during a standard physical examination.

Current recommendations state that the following patients should be urgently referred for a urological assessment: adults over 45 years old with unexplained visible haematuria not caused by a urinary tract infection, adults over 45 years old with visible haematuria that persists or recurs after successful treatment of a urinary tract infection, and adults aged 60 and over with unexplained non-visible haematuria and either dysuria or a raised white cell count on a blood test.

For those aged 60 and over with recurrent or persistent unexplained urinary tract infections, a non-urgent referral for bladder cancer is recommended.
