1. Hydrocele Definition: smooth, tense scrotal mass. accumulation of fluid within the tunica vaginalis surrounding the testicle; it may result from a patent processus vaginalis at birth and sometimes closes spontaneously within the first 1 to 2 years of life. Hydroceles are the most common cause of painless scrotal swelling.; in adults often the result of trauma, hernia, testicular tumor, torsion, or a complication of epididymitis. If present in man >30, may be secondary to a testicular tumor (red flag) Presenting Symptoms: Usually painless and may be present for long periods, partially resolve, and recur. Gradual enlargement of the scrotum occurs with marked edema, which may be uncomfortable d/t added weight. May occur secondary to a tumor when excess serous fluid accumulates in the scrotal sac. It will transilluminate but may make testicular palpation difficult. Leik Review: More common in infants. Serous fluid collects inside the tunica vaginalis. During scrotal exam, hydroceles are located superiorly and anterior to the testes and most are asymptomatic. If new-onset hydrocele in an adult or enlarging hydrocele, order scrotal ultrasound and refer to urologist. Differential Diagnoses: Epididymitis, Testicular torsion, epididymal cyst Review questions: 1. A patient who has had a swollen, nontender scrotum for one week is found to have a mass within the tunica vaginalis that transilluminates readily. The family nurse practitioner suspects: a.) a hydrocele. b.) a varicocele. c.) an indirect inguinal hernia. d.) carcinoma of the testis. 2.) Kidney Failure Acute Kidney Injury: (AKI) is potentially reversible kidney injury but can progress to failure. Defined as an increase in serum creatinine of 0.3 mg/dl over 48 hours, or an increase in Sr Creatinine to 1.5 (or >50% above baseline) times baseline over the past 7 days, or a urine volume output of <0.5ml/kg/hr for 6 hours. 3 classes as shown in table 131.4 on page 786. GFR: the higher the better the kidneys are working Uremia: s/s seen in severe AKI or ESKD and includes n/v, anorexia, fatigue, lethargy, confusion Azotemia: the lab finding of elevated SR urea (aka BUN in the usa) Pre-renal azotemia: an elevation of sr urea in the absence of an elevation in creatinine that is specifically d/t poor renal perfusion Prerenal: Occur upstream of the kidneys: d/t getting blood to the kidneys; dehydration, heart failure, liver failure Can be caused by diuretics, ACE/ARB, NSAID, calcineurin inhibitors Intrarenal: within the kidney; intrinsic renovascular disease (hypertensive emergency, small vessel vasculitis, TTP/HUS), Glomerular Disease (post- infectious glomerulonephritis), Tubulointerstitial disease (AC tubular necrosis which is caused by sepsis, meds, contrast, rhabdo, prolonged AKI, ac interstitial nephritis) Meds: Aminoglycosides, cisplatin, tenofovir, beta-lactams, vanco, Bactrim, NSAIDs, acyclovir, methotrexate Postrenal: impaired urine drainage: obstruction: Ureteral obstruction (usually required bilateral), Neurogenic bladder (cannot generate contractions to empty bladder fully), UTI, Medications, BPH Meds: opiates, decongestants, antihistamines, antiemetics, SSRI Chronic Kidney Disease: (CKD): abnormalities in the kidney function for >3 months with health implications. Chronic Kidney failure (ESRD or Stage 5 CKD): The absence of kidney function. Characterized by anuria and the need for renal replacement therapy or kidney transplant. The kidneys and urinary tract system no longer filter blood, create filtrate, or excrete urine in amounts sufficient to clear waste and balance fluid intake with output. Key highlights: Proteinuria or hematuria, and /or a reduction in the GFR, for > 3 months. The most common causes are diabetes mellitus (#1) and HTN, therefor monitor for kidney function in these patients. Most people are asymptomatic and the diagnosis is determined only by laboratory studies. Differential diagnosis: obstructive uropathy, nephrotic syndrome, glomerulonephritis Presentation: AKI and CKD have very few symptoms early on. Diagnostics: GFR and SR Creat first thing in the morning, or a random urine sample to assess for Albuminuria Hallmark of AKI and CKD: ¯GFR, SR Creatinine, albumin in urine Imaging: Renal US to evaluate presence of obstruction, bladder US to evaluate PVR, Renal biopsy for glomerular disease diagnosis. Pharmacologic Mngt: Remove sources of nephrotoxins (contrast/drugs), and manage fluids to avoid over/underhydration. Early recognition/treatment of electrolyte imbalances, especially hyperkalemia. Mngt includes control of HTN (130/80), ¯proteinuria with diet. ACE inhibitors are recommended to slow progression of CKD. Treat acidosis with supplemental bicarbonate and attaining glycemic control (A1c <7 and increases to 8.5 in older and ill adults) also associated with slowing CKD progression. Non-Pharmacologic: Protein diet restriction (0.6-0.8 g/kg/day), smoking cessation. Referral to nephrologist. Replace calcium and vitamin d when necessary. Manage lipids. Incontinence: Stress Incont: Leakage of urine with any maneuvers that increase intra- Abd. Pressure oNonpharmacy Treatment: Behavioral therapies (timed or double voiding, smoking cessation, wt. loss, pelvic muscle exercise with or w/o PT, pessary, bowel management; Pharm: alpha adrenergic agonists, tricyclic antidep., estrogen; Surgical: injectables, bladder neck suspensions, slings, artificial sphincters Urge Incont.: Sudden uncontrollable sensation to void that leads to incontinence. Most common in older adults o Nonpharmacy: bladder training, scheduled voiding, bladder irritant minimization, urge suppression; Pharm: anticholinergic- antimuscarinics, vaginal estrogen; Surg: neuro-sacral modulation, bladder augmentation, botulinum toxin injections Mixed: Combo of both stress and urge Overflow Incont: incomplete emptying of urine often results in passive loss of small amounts of urine when bladder pressures elevate and bladder fills beyond capacity........
