COLORECTAL QUIZ: June 6, 2022

Ron Reeder • June 6, 2022

Happy June!


Last week, I asked you about the foley removal after a PSARP with rectourethral fistula.

A few considerations – what was the repair – rectobulbar? Prostatic? Bladderneck?

How is the spine – patients with tethered cord are more likely to have urinary retention.

I leave a foley for 7 days, but many of you removed the foley sooner, which is probably just fine.

If the patient does not void I would try a single gentle insertion using a Coudet. If that doesn’t go easily you have two choices – cystoscopy with placement of a foley over a wire (you need to use an end hole catheter (Counsel tip) or create one (with the angiocath trick). Or place an s/p tube. Usually this retention is self limited and the patient starts voiding on their own. Sometimes intermittent cathing needs to be started.

Ok, now for this week:


You see a patient who underwent a PSARP, who has a severe stricture of the anoplasty about 2 cm deep, the colostomy remains in place. The anus is properly located. She has an intact vaginal septum.


What would you do?  Redo of anus – but how? The anus is well located?  Management of vaginal septum?

Colorectal Conundrum: January 29, 2024

By Ron Reeder • January 29, 2024
Colorectal Conundrum for January 29: A male with a rectoperineal fistula undergoes a PSARP with mobilization of the rectum, both anterior and posterior rectal walls. In the days following surgery he starts to drain urine around the anoplasty consistent with a urethral injury. He is also voiding via the penis. A cystogram is shown below. How would you manage this situation? Answer: This patient has suffered from a urethral injury, and urine is draining out the posterior urethra into the perineum around the anoplasty. The key first step is to divert the urine with a suprapubic tube. A colostomy is not necessarily needed. The fistula might heal with diversion. If after a month or so a cystogram shows the persistence of the fistula, then a redo is needed with re-mobilization of the rectum, fully lifting the anterior rectal wall off of the urinary tract, and repair the urethra, with coverage of the posterior urethra with an ischiorectal fat pad. Then a voiding trial a month later with ultimate removal of the SP tube.

Colorectal Conundrum: January 22, 2024

By Ron Reeder • January 22, 2024
Colorectal Conundrum for January 22nd: In the previous week’s case, of an imperforate hymen, the MRI showed dilation all the way down to the perineum. Management involved a perineal – introital – incision to drain the fluid. If that were not the case and you had a dilated vagina but the distal extent was far away from the introital area, how might you handle that hydrocolpos? Answer: If this were a case of hydrolpos with normal anus and normal urethra, and the vagina cannot be drained by the introitus like an imperforate hymen, then drainage needs to be from above. IR or laparoscopy is an ideal approach to get a drain in the dilated structure (remember this could be bilateral, so both sides may need to be drained. Drainage is to relieve distension and most concerning its potential cause of distal ureteral obstruction causing hydronephrosis. Once the material hormones have dissipated the hydrocolpos will resolve and can be dealt with later in life via a laparoscopic distal vaginal pull-through, after the onset of puberty. In such a patient, I would follow closely with ultrasound 6 months after thelarche (breast budding).

Colorectal Conundrum: January 16, 2024

By Ron Reeder • January 16, 2024
Colorectal Conundrum for January 16: A newborn female is noted to have abdominal distension. On exam the uretha and anus are normal, and there appears to be a bulge in the hymen. The has an MRI with the image shown below. What would be your treatment plan? What are the variations in such a case and how would you manage each? Answer: This could be a case of imperforate hymen, but the MRI is key – how high up is the obstruction? How large is the hydrocolpos? In this case, it appears that a perineal incision might all that is needed as the dilation extends all the way down to the perineum. That is the most common scenario. An incision at the level of the hymen should drain out the fluid and no further intervention should be needed. Of course a careful exam needs to check to be certain you see a urethra – sometimes such a bulge could be a paraurethral cyst. For the next week’s question – what would you do if the perineal approach was inadequate – i.e. could not reach the dilated lumen.
