prostate cyst
Introduction
Introduction to prostate cyst Prostate cysts have congenital cysts and acquired cysts, and congenital cysts have two cases, one is the cyst on the prostate capsule, called the prostate cyst, and the other is the congenital cyst of the prostate itself. The former is more common than the latter. The symptoms of the patient vary according to the size of the cyst. The light can be completely asymptomatic. In severe cases, there may be urinary urgency, urination, urinary tract, fine residual urine and urinary retention. Hematuria is rare. When the cyst is complicated by infection. Pyuria can occur. basic knowledge The proportion of illness: 0.084% (the probability of illness over 40 years old is 21%) Susceptible people: male Mode of infection: non-infectious Complications: hypospadias cryptorchidism renal hypoplasia
Cause
Causes of prostate cysts
Congenital factors (30%):
The congenital cyst of the prostate cyst occurs in the residual part of the middle or the middle renal tube system, and the cyst wall is composed of fibromuscular tissue; the acquired cyst is mostly due to incomplete obstruction of the prostate acinus to form a retention cyst, and the acinar epithelium becomes thin. The wall of the cyst is a fibrous muscle tissue covered by a cubic epithelium. The cystic fluid is mucus and may have sperm.
Endocrine disorders (30%):
Originated from the fusion end of the Müller tube, and is considered to be similar to the female uterus and the upper part of the vagina, it is called the male uterus, and some authors believe that the prostate sac is a urinary sinus dorsal wall extending toward the back side. A sachet, which may be the equivalent of a vagina, which may form a cyst that may be formed in two situations:
1 Because there are more parts of the end of the middle renal bypass tube (such as retention to the uterus or even the fallopian tube), in some male pseudohermaphroditism, the preservation of the entire middle and adjacent renal tube structure is sometimes seen.
2 In a small number of cases, the prostate cyst is dilated due to weak or temporary endocrine balance disorder, which causes hypertrophy and leads to the formation of cysts.
Prevention
Prostate cyst prevention
1. Pay attention to personal hygiene and wash your lower body every night.
2. Maintain a good mood, be optimistic and open-minded, and promptly resolve your bad feelings.
3. Drink plenty of water, drink at least 7 glasses of water a day (about 2000 ml) and get a glass of water (70 ml) after getting up every morning.
4. Sit down and sit up for an hour or so.
Complication
Prostatic cyst complications Complications hypospadias cryptorchidism renal hypoplasia
May be associated with other urinary malformations, such as hypospadias, cryptorchidism, renal hypoplasia and other congenital diseases.
Symptom
Symptoms of prostate cysts Common symptoms Male abdominal pain, urgency, pyuria, urinary cysts
The symptoms of the patient vary according to the size of the cyst. The light can be completely asymptomatic. In severe cases, there may be urinary urgency, urination, urinary tract, fine residual urine and urinary retention. Hematuria is rare. When the cyst is complicated by infection. Pyuria can occur.
Examine
Examination of prostate cysts
1. Cystoscopy can be seen in a semi-circular diameter of 1 ~ 2cm, or a rounded transparent mass, protruding in the bladder neck, mostly acquired cysts.
2. X-ray inspection
(1) intravenous urography: urinary malformations can be found, such as kidney development.
(2) urethrography: because the cyst and the urethra do not communicate, no display, no abnormal findings.
3. B-mode ultrasonography can be found in the prostate area with a smooth inner wall, clear edges, circular or elliptical translucent areas without internal echoes, and transrectal ultrasound showing a clear, circular, anechoic zone extending from the center of the prostate to the posterior superior It is in the form of a teardrop, and it is connected to Jingjing by a small pedicle.
4. CT examination of large cysts of the prostate and Müllerian cysts, located in the posterior part of the midline of the prostate, is a round, clear cystic lesion with a water-like density.
5. If the cyst is too large, the cystic fluid can be withdrawn through the rectum or perineal puncture. The acquired cyst is a clear mucus, which can also be dark brown or bloody. The cyst fluid can contain sperm.
Diagnosis
Diagnosis and differentiation of prostate cyst
diagnosis
When the cyst is small, there is no clinical manifestation, it is difficult to find and diagnose, and it is inadvertently found when other related diseases are performed. When the cyst is large, it causes different degrees of lower urinary tract obstruction. The rectal examination can be performed. The cyst is swollen at the midline of the prostate. The cyst can be found in the abdomen.
Differential diagnosis
1. Seminal vesicle cysts may have frequent urination, urgency, dysuria and other symptoms. The rectal examination may be performed on the side of the prostate and cystic mass. The mass is single, the edge is smooth and complete, and the cyst fluid may contain sperm; Lateral vas deferens retrograde or direct percutaneous transluminal angiography showed compression of the seminal vesicle, filling defects and circular shadows of the cyst.
2. Hydatid cysts rectal examination can be used in the prostate area and tumors, but the hydatid cysts occur in the prostate, most of them in the bladder and rectum or bladder wall, can adhere to the prostate, eosinophils increased The hydatid antigen is positive in the intradermal test or the complement binding test.
3. Prostatic sinus (diverticulum) and prostate cysts have similar performance, but different: early symptoms, in infants, adolescence; often associated with hypospadias, cryptorchidism and pseudohermaphroditism and other congenital anomalies; urethrography can show The posterior urethra communicates, and when the rectal massage is performed, liquid is often discharged from the urethra and is easily infected.
