[PMID: 39302474 DOI: 10.1007/s00345-024-05209-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Accepted: 08/05/2024] [Indexed: 09/22/2024] Open
Abstract
PURPOSE To develop a novel adaptation of the Whitaker test for assessing the surgical effects of ileal ureter replacement (IUR), and to evaluate its feasibility and effect in the postoperative evaluation. PATIENTS AND METHODS From November 2021 to September 2023, patients undergoing the modified Whitaker test following IUR were prospectively enrolled. The relative pressure was defined as the pelvis pressure minus the bladder pressure. Successful nephrostomy removal was defined as absence of symptoms and improved or stable hydronephrosis. RESULTS The 51 ureters from 39 patients underwent the modified Whitaker test after IUR. The modified Whitaker test was performed successfully on all patients without any reported discomfort. The relative pressure of 47 ureters kept steady (< 15 cmH2O) throughout the examination with well ileal ureter peristalsis and was classified into type I. The relative pressure of 2 ureters increased with perfusion reaching a range of 15-22 cmH2O, with well ileal ureteral peristalsis observed (type II). The relative pressure of 2 ureters increased along with perfusion, with weakening of ileal ureter peristalsis or a leakage of contrast medium, and the relative pressure surpassed 22 cmH2O (type III). Nephrostomy tubes were promptly removed for type I and type II ureters, while removal for type III ureters occurred after a 2-month period. None of the 39 patients required additional interventions for recurrent obstruction. CONCLUSION The modified Whitaker test was a safe and effective approach for the evaluation of surgical effects of IUR, offering additional evidence to assess the safety of nephrostomy tube removal.

BMC Urol 2024; 24:118. [PMID: 38858691 PMCID: PMC11163719 DOI: 10.1186/s12894-024-01509-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Accepted: 06/04/2024] [Indexed: 06/12/2024] Open
Abstract
PURPOSE To present the experience of ileal ureter with ileocystoplasty (IUC), and compare the outcomes of IUC in minimally invasive procedures to open procedures. PATIENTS AND METHODS From December 2017 to April 2023, twenty patients underwent IUC in open or minimally invasive (including laparoscopic and robotic) procedures. The baseline characteristics, perioperative data and follow-up outcomes were collected. Success was defined as relief of clinical symptoms, stable postoperative serum creatine and absence of radiographic obstruction. The perioperative and follow-up outcomes of open procedures and minimally invasive procedures were compared. RESULTS The etiology included pelvic irradiation (14/20), urinary tuberculosis (3/20) and surgical injury (3/20). Bilateral ureter strictures were repaired in 15 cases. The surgeries conducted consisted of open procedures in 9 patients and minimally invasive procedures in 11 patients. Compared to open procedures, minimally invasive surgeries had less median estimated blood loss (EBL) (100 ml vs. 300 min, p = 0.010) and shorter postoperative hospitalization (27 d vs. 13 d, p = 0.004). Two patients in the open group experienced grade 3 complications (sigmoid fistula and acute cholecystitis in one patient, and pulmonary embolism in another patient). Over a median follow-up period of 20.1 months, the median bladder functional capacity was 300 ml, with a 100% success rate of IUC. CONCLUSION IUC is feasible in both open and minimally invasive procedures, with acceptable complications and a high success rate. Minimally invasive procedures can have less EBL and shorter postoperative hospitalization than open procedure. However, prospective studies with larger groups and longer follow-up are needed.

Int Urol Nephrol 2024; 56:1817-1824. [PMID: 38285099 DOI: 10.1007/s11255-023-03927-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 12/17/2023] [Indexed: 01/30/2024]
Abstract
PURPOSE To explore the role of the Whitaker test in evaluating the postoperative outcome of upper urinary tract reconstruction surgery in patients carrying a nephrostomy tube after surgery. PATIENTS AND METHODS This was a prospective observational study performed in 42 patients with nephrostomy tube undergoing the Whitaker test after upper urinary tract reconstruction surgery between January 2020 and December 2021. Data on clinical information, the Whitaker test and surgical procedure were collected prospectively, and the long-term follow-up results were analysed retrospectively. RESULTS The 46 ureters of 42 patients (right 16, left 22, bilateral 4) underwent six common upper urinary tract surgical reconstruction procedures and one combined procedure, including pyeloplasty, ureteroureterostomy, lingual mucosal onlay graft, appendiceal onlay flap, ureteral reimplantation, Boari flap, and ipsilateral lingual mucosal onlay graft combined ureteral reimplantation. All patients underwent the Whitaker test successfully without any discomfort after examination. The postoperative Whitaker test showed 43 kidneys without obstruction and 3 kidneys with obstruction. At a median follow-up of 18 months (range 13-31), the follow-up results showed that the overall success rate of the surgery was 100% (46/46). Concerning the concordance Whitaker test and follow-up results, the observed proportion of agreement was 93.5% (43/46). CONCLUSION The Whitaker test can achieve similar consistency with the long-term follow-up results after upper urinary tract reconstruction surgery and can be used as a tool to evaluate the surgical efficacy of upper urinary tract reconstruction surgery, which can provide a prognostic efficacy evaluation for patients carrying a nephrostomy tube after surgery.

Cine magnetic resonance urography and Whitaker test: dynamic visualized and quantified tools in ileal ureter replacement. Transl Androl Urol 2022; 10:4110-4119. [PMID: 34984177 PMCID: PMC8661268 DOI: 10.21037/tau-21-507] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Accepted: 09/18/2021] [Indexed: 11/18/2022] Open
Abstract
Background To assess the feasibility and usefulness of cine magnetic resonance urography (MRU) and Whitaker test as postoperative evaluation tools of ileal ureter replacement. Methods We retrospectively collected the medical records of 42 patients who underwent ileal ureter replacement between August 2015 and August 2020. The morphology, luminal diameter, amplitude, contraction ratio, peristaltic frequency, ureteral jets and peristalsis efficiency were recorded in cine MRU. Under different perfusion loads, image and pressure changes of the reconstructed upper urinary tract were recorded in the Whitaker test. Patients were categorized into normal pressure and elevated pressure groups. Results A total of 42 patients underwent cine MRU, and 20 of them finished the Whitaker test successfully. The mean amplitude was 9.29±3.51 mm, and the contraction ratio was 0.607 (0.247–0.790). The median peristaltic efficiency was 0.75 (0.29–1). Three patients presented an unusual rise in renal pelvis pressure, which was 54, 26, 57 cmH2O respectively. The amplitude of the ileal graft in the elevated pressure group was larger (13.80±5.73 vs. 8.09±3.38 mm, P=0.024), the contraction ratio was higher [0.68 (0.59–0.79) vs. 0.59 (0.25–0.79), P=0.028], the peristaltic frequency was more active [7 (6–8) vs. 4 (3–8), P=0.025], but the peristaltic efficiency was lower [0.50 (0.29–0.50) vs. 0.75 (0.33–1), P=0.029] compared to the normal pressure group. There were no significant differences in the ureteral jets [3 (2–4) vs. 3 (1–7), P=0.840), creatinine (97.3±7.3 vs. 103.2±30.7 µmol/L, P=0.753), and estimated glomerular filtration rate (eGFR) (76.4±14.1 vs. 68.5±28.7 mL/min·1.73 m2, P=0.663). Conclusions Cine MRU provides morphological and peristaltic motility of the ileal graft, cine MRU after ileal ureter replacement was recommended as a routine examination. The Whitaker test represents a complementary investigation to evaluate pressure changes to reveal the ability to transport urine, and it can be used as a supplementary examination to clarify equivocal cases.
