Pyocystis: a systematic review

Single-dose intravesical amikacin instillation for pyocystis in a patient with autonomic dysreflexia: A case report

CONTEXT

Pyocystis is an infection of the epithelium of the bladder and a frequent complication of anuria. Patients with spinal cord injury (SCI) at the sixth thoracic vertebra (T6) or higher are at a greater risk for autonomic dysreflexia (AD), which can be induced by infections such as pyocystis. Cases of pyocystis treatment with aminoglycoside instillations have been reported in the literature.

FINDINGS

We describe the case of a 59-year-old male with T1 American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade A complete paraplegia, status post bilateral nephrectomy with recurrent episodes of AD suspected to be caused by pyocystis related to anuria. A bladder specimen culture grew Escherichia coli susceptible to amikacin with a minimum inhibitory concentration (MIC) of ≤ 8 mg/L. In the setting of anuria and with concern that intravenous antibiotics would not adequately reach the site of infection, we chose to treat the patient with a single-dose intravesical instillation of amikacin 25 mg/100 mL left to dwell for approximately 2 h. A repeat bladder culture showed no colonies. The patient remained stable with no episodes of AD and no signs or symptoms of infection one month following treatment.

CONCLUSION

The purpose of this case report is to add to the current literature on intravesical aminoglycoside instillations for pyocystis to aid clinicians in treating future cases, as well as to highlight pyocystis as a potential cause of AD in SCI patients with anuria.

Management of Bladder Pain Syndrome (BPS): A Practical Guide

Bladder pain syndrome (BPS) is a prevalent and pervasive disease. The physical and psychological sequelae can be very burdensome for the patient, and the condition represents a real challenge for the clinician as well. With no simple pathognomonic test, finding harmony in navigating patient care can be demanding. Diagnosis and management rely upon a multidisciplinary and holistic approach. Treatment options include conservative measures and pharmacotherapies as well as bladder instillation therapies. Ultimately, surgery may be offered but only in cases of refractory disease. This article offers a pragmatic guide for clinicians managing this challenging disease.

Cystectomy and ileal conduit for neurogenic bladder: Comparison of the open, laparoscopic and robotic approaches

AIM

The objective of the present study was to compare the outcomes of open versus laparoscopic versus robotic cystectomy and ileal conduit for neurogenic lower urinary tract dysfunction (NLUTD).

METHODS

The charts of all patients who underwent cystectomy and ileal conduit for NLUTD between January 2004 and November 2020 in an academic center were retrospectively reviewed. The approach was either open, laparoscopic or robot-assisted depending on the period (i.e., three consecutive era). For the robotic approach, the diversion was done either intracorporeally or extracorporeally. We compared the perioperative and late postoperative outcomes between the three groups.

RESULTS

After exclusion of 10 patients with non-neurogenic benign conditions, 126 patients were included over the study period. The most frequent neurological conditions were multiple sclerosis (36.5%) and spinal cord injury (25.4%). The approach was open, laparoscopic or robot-assisted in 31 (24.6%), 26 (20.6%) and 69 (54.7%) cases respectively. Seventy-two patients experienced a 90-day postoperative complication (57.1%) of which 22 had a major complication (Clavien 3 or higher, 17.5%) including one death (0.8%). The rate of major postoperative complications was significantly lower in the robotic group (23% vs. 23% vs. 10%; p = 0.049) while the rate of overall complications was comparable across the three groups (58.1% vs. 53.9% vs. 60.6%; p = 0.84). After a median follow-up of 23 months, 22 patients presented a late complication (17.6%), mainly incisional hernia (5; 4%) and uretero-ileal stricture (9; 7.2%). The rate of late complications did not differ significantly between the three approaches.

CONCLUSION

Cystectomy and ileal conduit for neurogenic bladder is associated with a relatively high perioperative morbidity. The robot-assisted approach may decrease the risk of major postoperative complications.
