SURGICAL APPROACHES
Several approaches can be used to remove the hypertrophied portion of the prostate gland:
CLOSED Transurethral resection of the prostate (TURP), Transurethral incision of the prostate (TUIP)OPEN Suprapubic prostatectomy, Perineal prostatectomy, Retropubic prostatectomy, and
![Page 12: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/12.jpg)
SUPRAPUBIC PROSTATECTOMY
Suprapubic prostatectomy is one method of removing the gland through an abdominal incision. An incision is made into the bladder, and the prostate gland is removed from above.
![Page 13: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/13.jpg)
PERINEAL PROSTATECTOMY
Perineal prostatectomy involves removing the gland through an incision in the perineum. This approach is practical when other approaches are not possible and is useful for an open biopsy.
![Page 14: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/14.jpg)
RETROPUBIC PROSTATECTOMY
Retropubic prostatectomy, another technique, is more common than the suprapubic approach. The surgeon makes a low abdominal incision and approaches the prostate gland between the pubic arch and the bladder without entering the bladder

TRANSURETHRAL RESECTION OF THE PROSTATE(TURP)
Removal of prostate tissue using a resectoscope inserted through the urethra (excision and cauterisation) under spinal or general anaesthesia
![Page 16: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/16.jpg)
TRANSURETHRAL INCISION OF THE PROSTATE(TUIP)
Done under LA. Indicated for men with moderate s/s with small enlargement and who are poor surgical candidates
![Page 17: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/17.jpg)
MINIMALLY INVASIVE THERAPY
Transurethral microwave thermotherapy (TUMT)
An outpatient procedure of delivery microwaves directly to the prostate through a transurethral probe. (113°F/ 45°C)
Transurethral needle ablation (TUNA)
Low wave radio frequency is used to heat prostate gland with the help of a needle providing greater precision.

NURSING MANAGEMENT
GOALS Restoration of urinary drainage Treatment of UTI Understanding of procedures
![Page 20: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/20.jpg)
PREOPERATIVE INTERVENTIONS
Avoid alcohol and caffeine Avoid cold as it causes smooth muscle contraction Advise to urinate in every 2-3 hrs Normal fluid intake to avoid fluid intake &
volume overload. Catheterisation Antibiotic before any invasive procedures
![Page 21: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/21.jpg)
POSTOPERATIVE
main complications- hemorrhage, bladder spasms, urinary incontinence, infections
Bladder irrigations with normal saline [pink, no clots]
Monitor inflow & outflow of irrigant Catheter care avoid activities that increase the abdominal
pressure To relieve bladder spasms- opium suppositories,
antispasmodics with relaxation techniques.
![Page 22: Benign Prostate Hypertrophy for nursing students](https://reader035.vdocuments.pub/reader035/viewer/2022062702/554af17db4c905fc0e8b46a1/html5/thumbnails/22.jpg)
After catheter removal, patient should urinate within 6hrs
Patient should practice pelvic floor muscle technique (Kegel exercise)
Encourage to practice starting and stopping the stream during urination
Dietary management – fiber and easily digestible food Stool softners Avoid straining during defecation Avoid heavy weightlifting Sexual counseling
