Hydrocele Nursing Care Planning and Management Study Guide

A hydrocele is fluid collecting in the tunica vaginalis around the testicle, giving a painless scrotal swelling. Most are benign, and in infants most resolve on their own, so the real clinical work is distinguishing a simple hydrocele from a hernia or a testicular mass, and supporting the family through the watch-and-wait or, if needed, the surgical repair. The key bedside finding is a soft, nontender swelling that transilluminates.

What is Hydrocele

A hydrocele is a collection of peritoneal fluid in the scrotum, reaching it through a small passage called the processus vaginalis, the finger-like inguinal-canal projection through which the testes descend. The fluid sits within the tunica vaginalis of the scrotum or along the spermatic cord and represents either a persistent developmental connection along the cord or an imbalance of fluid production versus absorption. Galen described the connection of the abdominal cavity parietes to the tunica vaginalis in 176 AD, but clear inguinal anatomy and its relationship to groin hernias and hydroceles was not recorded until the 19th century.

Pathophysiology

A hydrocele requires an imbalance between scrotal fluid production and absorption, which can come from exogenous fluid sources or intrinsic fluid production, and the lesion can also be split by whether it keeps a patent communication with the abdominal cavity. In communicating hydroceles the excess fluid is exogenous (from the abdomen), while noncommunicating hydroceles build up fluid from abnormal intrinsic scrotal shifts. In communicating hydroceles, simple Valsalva maneuvers probably account for the classic change in size across day-sleep cycles. Noncommunicating hydroceles result from increased fluid production or impaired absorption. Sudden scrotal hydrocele in older children has followed viral illness, where viral-mediated serositis may drive the net fluid increase, and posttraumatic hydroceles likely come from increased serosal fluid production due to underlying inflammation. Rare in the United States, filarial infestation is the classic cause of decreased lymphatic absorption producing hydroceles.

Statistics and Incidences

A patent processus vaginalis is present in 80 to 90% of term male infants at birth. That frequency falls steadily until age 2 years, where it plateaus at about 25 to 40%, and autopsy series of men have found the processus remaining patent in 20% into late life. Clinically apparent scrotal hydroceles, however, are evident in only 6% of term males beyond the newborn period. The incidence in men is less well known.

Causes

In children, most hydroceles are communicating: a patent processus vaginalis lets peritoneal fluid flow into the scrotum, especially during Valsalva. In adults worldwide, filariasis, a parasitic infection from Wuchereria bancrofti, accounts for most hydroceles, affecting more than 120 million people in more than 73 countries. Iatrogenic hydroceles can follow laparoscopic or transplant surgery in males when inadequate irrigation-fluid aspiration leaves fluid in a patent processus vaginalis or small hernia.

Clinical Manifestations

A hydrocele typically presents as a soft, nontender fullness within the hemiscrotum. With a focused beam of light the scrotum transilluminates, giving a homogeneous glow without internal shadows. Hydroceles of the canal of Nuck in female patients present as soft, nontender inguinal or labial swelling.

Assessment and Diagnostic Findings

Simple hydroceles are diagnosed clinically. Few if any lab tests are warranted specifically for simple hydroceles, communicating or noncommunicating, though concomitant medical conditions may call for preoperative labs or studies to exclude other conditions in the differential. Ultrasonography gives excellent detail of the testicular parenchyma, cleanly distinguishes spermatoceles from hydroceles, and is an excellent screening study if a testicular tumor is a consideration. Duplex ultrasonography adds information on testicular blood flow when a hydrocele may be associated with chronic torsion. Plain abdominal radiography can help distinguish an acute hydrocele from an incarcerated hernia, where gas overlying the groin may indicate incarceration.

Surgical Management

Surgery uses three approaches: inguinal, scrotal, and sclerotherapy. The inguinal approach, with ligation of the processus vaginalis high within the internal inguinal ring, is the procedure of choice for pediatric hydroceles, and is mandated with high control and ligation of the cord structures if a testicular tumor is found on ultrasonography. The scrotal approach, with excision or eversion and suturing of the tunica vaginalis, is recommended for chronic noncommunicating hydroceles and should be avoided with any suspicion of underlying malignancy. Sclerotherapy, scrotal aspiration plus instillation of tetracycline or doxycycline solutions, is an adjunct or last resort: recurrence is common, as are significant pain and epididymal obstruction, so it is reserved for poor surgical candidates with symptomatic hydroceles and for men in whom fertility no longer matters.

Nursing Management

Nursing Assessment

On exam, the scrotum is enlarged on both sides, and a smooth, cystic-feeling mass that completely surrounds the testicle without involving the spermatic cord is characteristic of a hydrocele.

Nursing Diagnoses

Excess fluid volume related to fluid in the scrotal sac. Acute pain related to the postoperative wound. Risk for infection related to the surgical incision. Impaired urinary elimination related to the postoperative wound. Fear or anxiety related to the surgical procedure.

Nursing Care Planning and Goals

The patient or caregivers acknowledge feelings and identify healthy ways to handle them; the patient appears relaxed and rests and sleeps appropriately; caregivers identify risk factors and interventions to reduce infection and maintain a safe aseptic environment; the patient shows adequate fluid balance (stable vital signs, good-quality palpable pulses, normal skin turgor, moist mucous membranes, appropriate urinary output); the patient reports relief from pain; and the wound heals in a timely way.

Nursing Interventions

For health education, provide preoperative teaching, including a visit with OR personnel before surgery when possible, and walk through what may worry the patient: masks, lights, IVs, BP cuff, electrodes, bovie pad, the feel of an oxygen cannula or mask, autoclave and suction noises, and a crying child. To reduce infection risk, verify that preoperative skin, vaginal, and bowel cleansing have been done per the specific procedure, apply a sterile dressing to protect the fresh wound, and give antibiotics as indicated. To monitor fluid volume, measure and record I&O (including tubes and drains), watch vital signs for changes in blood pressure, heart rate and rhythm, and respirations, and resume oral intake gradually as indicated. For pain, evaluate it regularly (every 2 hours, noting characteristics, location, and intensity on a 0 to 10 scale), note anxiety or fear and relate it to the procedure and preparation, assess for causes of discomfort other than the operation, and add comfort measures such as backrub and heat or cold applications.

Evaluation

Goals are met when the patient or caregivers acknowledged feelings and healthy coping, the patient appeared relaxed and rested well, caregivers identified risk factors and maintained a safe aseptic environment, the patient showed adequate fluid balance, reported relief from pain, and the wound healed in a timely way.

Documentation Guidelines

Document individual findings (contributing factors, interactions, nature of social exchanges, specifics of behavior), intake and output, signs of infection, cultural and religious beliefs and expectations, the plan of care, the teaching plan, responses to interventions and teaching, and attainment or progress toward outcomes.
