   Abstract 

Some of the patients with genitourinary tuberculosis (GUTB) present to the urologist with small contracted bladders or with significant renal damage. [1] Additional reconstructive procedures are often required along with anti-tubercular treatment in these patients. These procedures commonly performed via the open approach, now have the advantage of minimally invasive approach provided by laparoscopic and robotic surgery. The technique of robot-assisted laparoscopic augmentation ileocystoplasty in a patient with a small contracted bladder due to GUTB will be described. The procedure was performed via a completely intra-corporeal technique using an ileal "cap" created from a 15 cm segment of distal ileum which was anastomosed to the urinary bladder bi-valved in the mid-sagittal plane. The procedure lasted for 420 minutes and the patient was discharged on postoperative day 5. At 6 month follow-up, the patient has no irritative urinary symptoms and voiding with insignificant post-void residual urine.

   Introduction Top


The involvement of the urinary bladder in patients with genitourinary tuberculosis is characteristic with the appearance of thimble bladder in the latter stages. Anti-tubercular therapy can help to limit the inflammatory processes within the bladder to a certain extent. However, in a small capacity thimble bladder, the performance of augmentation cystoplasty becomes a must in order to relieve the irritative lower urinary tract symptoms as well as prevent upper tract deterioration. [2]

Augmentation cystoplasty is commonly performed using a patch of the bowel to augment the urinary bladder. The most commonly used segments of the bowel are ileum, sigmoid colon, stomach, the ileo-caecal segment, and caecum. [2] It is general practice to perform it through the open approach owing to the technical complexity of the procedure. [3] The minimally invasive interest in this procedure started with the standard laparoscopic approach, which then paved way for the use of the robotics. The use of robotics has a unique advantage of providing greater degree of instrument freedom, and thus has been proposed to provide suturing advantages during the enterocystoplasty procedure. [4]

We present our experience with this technically demanding procedure in a patient of small capacity contracted bladder secondary to genitourinary tuberculosis. To our knowledge, this is the first application of robotic enterocystoplasty in a case of tubercular bladder.


   Case Report Top


A 43-year-old gentleman presented to us with a history of increasing frequency of micturition, nocturia, urgency, and urge incontinence for a period of 4 years. He had already undergone transurethral resection of prostate at another center without any symptomatic improvement and was subsequently evaluated and found to have genitourinary tuberculosis based on positive urine AFB stain and urine for TB PCR and then put on anti-tubercular therapy (ATT) for 6 months. Post ATT, the patient persisted to have these symptoms although to a lesser extent. A repeat urinary AFB stain was negative but a cystogram revealed a very low capacity (100 ml) urinary bladder [Figure 1]. An ultrasound and intravenous urogram (IVU) showed normal upper tracts. The patient was thus taken up for robot-assisted laparoscopic augmentation ileocystoplasty.

Technique

Pneumoperitonem and port insertion

Pneumoperitoneum was created using the Verres' needle and a total of six ports including two robotic ports were inserted [Figure 2]. Two assistant ports were used in the left side (12 mm and 5 mm) and a 12-mm assistant port was used on the right side. The robot was docked and the procedure started.

Preparation of the ileal patch

A segment of the distal ileum was identified 15 cm from the ileoceacal junction and using stay sutures fixed to the anterior abdominal wall a 15 cm ileal loop was isolated [Figure 3]a using the ECHELON FLEX TM 60 ENDOPATH stapler (Ethicon Endo-Surgery). Robotic cautery hook and bipolar cautery was used to divide the mesentery. Ileo-ileal anastomosis was done using the same endoscopic stapler and the mesenteric window was closed with interrupted 3-0 silk sutures. The isolated ileal segment was prepared by first cutting the staple lines then by de-tubularizing along its anti-mesenteric border [Figure 3]b. The segment was then folded into a U shape and the medial as well as the lateral borders were sutured with each other using the polyglactin 3-0 sutures in a continuous fashion creating an ileal patch [Figure 3]c.

Cystostomy and augmentation cystoplasty

The bladder was distended by filling it with saline through the urethral catheter and then bi-valved by opening it in the mid-sagittal plane. A trocar supra-pubic catheter was inserted into the urinary bladder through the anterior abdominal wall under robotic guidance. The ileal patch was then sutured to the edges of the urinary bladder using 2-0 polyglactin sutures, starting from the posterior corner of the opened bladder and then progressing to the anterior corner in a continuous fashion from either side [Figure 3]d and [Figure 4]. An 18 French drain was kept in the pelvis behind the anastomosis.

The total operative time was 420 minutes and the estimated blood loss during the procedure was 200 ml. The patient was allowed orally on post-operative day 3, drain removed on day 5, and discharged on day 6. The per-urethral and supra-pubic catheters were sequentially removed after 3 weeks and residual urine volume assessed. At 6 months of follow-up, the patient has no irritative urinary symptoms and voiding with insignificant post-void residual urine.


   Discussion Top


Lymph node tuberculosis is the most common extrapulmonary form of tuberculosis; [5] however, genitourinary tuberculosis is also fairly common in India with an incidence of about 18%W The tubercular involvement of the urinary bladder may lead to the bladder becoming smaller, contracted, irregular, or even calcified and may eventually lead to autocystectomy. [6] In patients with tubercular thimble bladder, augmentation cystoplasty is performed to relieve the patient's intolerable symptoms due to the reduced bladder capacity and to prevent or stop renal damage. [2] At least 3-6 weeks of antitubercular therapy is indicated prior to undertaking of any reconstructive surgery to allow the inflammatory process to settle and the disease to stabilize as well as for better assessment in performing the appropriate procedure. [7]

Although commonly performed through the open technique, the use of minimally invasive approaches like laparoscopy and robot-assisted laparoscopy has been now employed especially in augmenting the neurogenic bladder. [3],[4],[8],[9] The first use of the laparoscopic technique was demonstrated by Docimo et al. [10] in 1995 by performing laparoscopic gastrocystoplasty, and Gill et al. [3] in 2000 broadened the horizons by applying the laparoscopic technique to the use of various other segments of the bowel. The laparoscopic technique has been used to perform both intracorporeal [11] and extracorporeal suturing [3],[10] to construct the bowel patch to be used for augmentation.

The surge in use of the robot in a variety of urological procedures has fueled the interest in the reconstructive procedures being performed robotically. The first report of robotic enterocystoplasty came from Al-Othman et al. [8] in 2008, where they used a completely intracorporeal technique for the performance of the procedure. Similarly, in the pediatric population, Gundeti et al. [12] described the performance of a completely intracorporeal robot-assisted laparoscopic augmentation ileocystoplasty along with appendico-vesicostomy in a pediatric patient. Since these initial reports a few other authors have also reported their experience with these especially in the population with neurogenic bladder. [4],[8],[9] The largest series till date has been that of Gould et al. [4] who reported their experience with five patients of neurogenic bladder who underwent robotic augmentation ileocystoplasty. In their experience, the operative time for the procedure gradually decreased with increasing experience (from 7.3 hours to 5.9 hours) and had minimal morbidity on short-term follow-up.

Our experience has been comparable with those already reported in the literature. The duration of the procedure at 7 hours is indeed an overwhelming one, but with increasing experience it is bound to decrease. The early post-operative recovery and the shortened hospital stay are important advantages that come in a long way in improving post-operative outcomes and the ease of performing the procedure for the surgeon due to the use of the robot adds to the advantage of the minimally invasive laparoscopic approach. This is the first reported experience to the best of our knowledge of robotic augmentation cystoplasty in a tubercular small contracted bladder where the bladder is known to become very thickened and dramatically reduced in size. [2],[6]

Robotic augmentation cystoplasty is a suitable and feasible option for patients with tubercular small contracted bladder. Increasing experience and longer follow up are required to further validate the use of the robot in performance of this procedure.
